...does not occur only if the protein is folded properly. It can occur in misfolded proteins, however, the ERAD system / calnexin will recognize the misfolded protein and decide to utilize ERAD to degrade the protein. See: Molinari, M. (2007).

Organization and Elaboration
Hello, I am yet another student editor that has reviewed this article as a Wiki supported course assignment. I wanted a chance to consult with everyone on the talk page about some improvements we can make to the article. I agree with the wikipedia B-class evaluation, high importance level, and over technical label. On a positive note the references seem extensive, and I see that wiki editors have done an accuracy check. However, my two main comments are on the elaboration and organization of certain sections. The parts that appear particularly incomplete are the history and clinical sections. I agree with a previous comment stating that the SER and RER are extremely different, however instead of an entirely new page for each type, maybe a more detailed distinction would be sufficient. However, in light of any future edits we might be able to make the article more digestible for the non science community with extensive elaboration on technical terms. For example, 17 hyperlinked words in the first paragraph alone might be frustrating for students to read. Next, the organization can be improved to help a non science reader follow the flow of ideas. One way to achieve this might be to reorganize the pictures. Maybe moving the TEM photo to the top so that it is the first thing they see. Also, describing the photos better in the text. The other way of organizing would be through text. Having more of an outline with headings and subsections could help. For example in the Function section having different sub-subsections for SER and RER as well as for plant and animal cells, because the details of the roles can differ. Let me know your thoughts!Nmenk (talk) 02:30, 30 September 2016 (UTC)
- @Nmenk: I'm curious as to why you think hyperlinked words, however many, "...might be frustrating for students to read." ? I find them extremely useful to quickly find out things I might not know much about. If your concern is that too much info sometimes pops up if the reader moves the mouse over the link, I think that's a wiki feature called Page Preview which can be enabled or disabled by the reader/user themself, and I have tried both & prefer disabled, so that problem doesn't happen for me. Users who are not logged in to wiki can turn Page Previews off via the cog-icon displayed at the bottom of each preview. Logged-in users can control their settings from two places. They may enable or disable Page Previews from the Appearance section of Special:Preferences (under "Users and rights", "Appearance", "Reading Preferences"). Logged-in users may also turn Page Previews off via the cog-icon displayed at the bottom of each preview. UnderEducatedGeezer (talk) 04:48, 23 May 2019 (UTC)
the SR is in cardiac muscle also, not just smooth and skeletal. some loser sort it out
Comments from BEFORE 2008
One should also include ERAD, the Endoplasmic Reticulum Associated Protein Degradation, and link to the short article explaining it. Since English is not my native language, it would be nice of someone could write a few sentences about it in this artice.

Smooth ER & Rough ER

Magnus, did you make that image yourself? That is incredible. --LMS
- Yup, from my "Nupedia evacuation". There are more like this :) --Magnus Manske
Suddenly your images are no longer in the page. (In the ribosome article this changed in the last couple of hours.) When I click on the hyperlink the image appears in its own page. Then I have to click the back and forward arrows to compare the image to the caption. Inconvenient. (Even if I could set my browser to display the image in its own window, or if you could program it into a pop up window, there will always be cases where, due to the size of the image and the location of the caption in page, I would have to click on the windows to compare the image to its caption.'
In this case, the text does not flow properly around the hyperlink to the image, unless I maximize the window. I see the text and the caption printed on top of each other.

- I think it's just a temporary glitch while the rules about what images can and cannot be shown are changed - somebody will sort it out in time. By the way, four or more hyphens, thus: ---- will make a horizonal rule, and a colon at the start of a line will indent it. --Camembert

Identification of the numbers from the image
These are the identifications needed:

- (2) Ribosomes
- (3) Pores (of the nucleus)
- (4) Nucleolus
- (5) Chromatin
- (6) Nucleo membrane
- (7) Endoplasmic reticulum
- (8) Nucleoplasma
NOTE: Because for numbers 5 and 8 it is not shown clearly (on the image) what are they pointing at, it can be vice-versa for the explanation.
- Those identifications aren't completely correct.

Shouldn't words like reticulum that have irregular plurals have their plurals indicated. I would have doen it, but with the 'ER' stuff, I didn't know where it would best be placed. Kdammers 08:29, 8 May 2006 (UTC)
I've decided to try sprotecting this for a while. It's been vandalised many times per day since the beginning of September, mostly with (individually trivial) additions of hoax info or graffiti. I really can't figure out why it's getting such attention - articles covered in school classes get a degree of the usual "Kevin is Kewl" type vandalism, but rarely this much. Blocking the anons is useless (it's rarely the same one twice) and we've not been succesful in detecting and removing all the vandalism (I just removed a couple of pieces that have been there for days, unnoticed). I'm guessing that maybe some website or noticeboard somewhere has a "wouldn't it be cool to put junk into the Wikipedia ER article"; on that theory I think we should sprotect it for a couple of weeks and see if the nonsense dies down. -- Finlay McWalter | Talk 14:49, 8 October 2006 (UTC)

I'm not exactly sure about all of this but according to my teacher, the SER also detoxifies drugs and breaks down glycogen into glucose(in liver cells). If the info is there, I'm just not seeing it but I don't even know if its correct. Also, why do you list many of the SER's functions under the structure heading? Arizonabass 20:42, 15 January 2007 (UTC)
I have checked quite a few secondary literatures, and am pretty sure that the SR is not only found in STRIATED MUSCLES but also SMOOTH MUSCLES. Please revise this bit of info in the article, LOL. Cheers126.96.36.199

Actually, this article really needs to expand on the role of the Sarcoplasmic reticulum and its role on EC coupling--this could be dedicated to its own article (i.e. the microanatomy of the SR and its role in muscle cells). Its name (in distinction to the ER, or the Smooth ER) reflects its specialized role in muscle compared to all other cells. —Preceding unsigned comment added by 184.108.40.206 (talk) 20:15, 19 November 2009 (UTC)

Layperson request for info
I read on some page in wikipedia this: "The endoplasmic reticulum is a synthesis and transport organelle that is an extension of the nuclear envelope." This refers to the ER's relationship to the nuclear envelope, and in general the nucleus. Could this relationship be put somewhere in the actual ER article, if this is factual? Thanks, Rhetth (talk) 20:57, 20 March 2008 (UTC)
"Insertion of proteins into the endoplasmic reticulum membrane: Integral proteins must be inserted into the endoplasmic reticulum membrane after they are synthesized. Insertion into the endoplasmic reticulum membrane requires the correct topogenic sequences."
This is incorrect. Co-translocational translocation occurs to integrate the proteins WHILE they are synthesised. Complete proteins are too large, folded and have insufficient hydrophobic access to the lipid bilayer, making it virtually impossible to insert them.
Also, it is unclear where the "topogenic sequences" exist. They are found in the nascent protein, not the ER membrane.
A revision is proposed:
Insertion of proteins into the endoplasmic reticulum membrane: Integral proteins must be inserted into the endoplasmic reticulum membrane while simultaneously being synthesized (co-translational translocation). Insertion into the endoplasmic reticulum membrane requires the correct topogenic signal sequences in the protein.

I think it is confusing that calcium storage in muscle cells is attributed to the smooth ER ("The smooth endoplasmic reticulum is known for its storage of calcium ions in muscle cells.") and than again in the next session to the sarcoplasmic ER. If somebody please help clarify this... -- xy (talk) 04:33, 15 October 2008 (UTC)
initial glycosylation as assembly continues. This is either N-linked (O-linking occur in the golgi).
This is not grammatically correct. It should read as:
Initial glycosylation occurs as assembly continues. This is N-linked (O-linking occurs in the golgi apparatus).
I cleaned it up some, but it is still confusing. Can anyone make it more clear? I know next to nothing about molecular biology, or for that matter, how to use wikipedia.

The RER is not always studded with these ribosomes, however; initially, the RER appears smooth due to a lack of resident ribosomes

Isn't it called endoplastic reticulum, not endoplasmic? That's what it's been called in all the biology textbooks we use in high school. I've never seen the word "endoplasmic" before. NoriMori (talk) 00:23, 4 February 2009 (UTC)

Identification of number 6 in the image
Currently the picture shows label 6 as "Proteins", but SER does not make proteins according to the page. I'm no expert, but this seems contradictory. Would it be more accurate to say "Hormones/lipids" or maybe "SER metabolic products"? 22.214.171.124 (talk) 01:13, 29 May 2010 (UTC)
"an eukaryotic" should be "a eukaryotic"
Shouldn't the pluralized spelling be "reticula?" 126.96.36.199 (talk) 02:51, 19 September 2010 (UTC)
ABSOLUTELY agree. It is bizarre and off-putting to keep referring to "the endoplasmic reticulum" as if there were a single such object per organism (like "the heart" or "the cranium"). This article ought to have non-specific plurals throughout: " Smooth endoplasmic reticula are abundantly found in mammalian liver and gonad cells. The lacey membranes of endoplasmic reticula were first seen by Keith R. Porter, Albert Claude, and Ernest F. Fullam in the year 1945."Sebum-n-soda (talk) 20:30, 2 June 2013 (UTC)
I don't think the smooth ER is connected to the nuclear envelope. If anything, the rough ER should be connected to it. Why is this written? On all of the other sites I researched, the smooth ER isn't connected. Could anybody verify this for me?

NNNNN== Cell Biology 322 ==
The article provides very brief understanding of both the Rough Endoplasmic Reticulum and the Smooth Endoplasmic reticulum. Under the portion of Rough Endoplasmic Reticulum section there were bullet point that were provided to understand the multiple key functions of the RER; however, the terms were much more higher level then they needed to be omitting clathrin, SNAP, and SNARE which are all terms that are unfamiliar will make this article more understanding. I believe taking out the bullet points would be beneficial to this article as well, this information can be provided in sentence form to help the reader better understand its importance.
Smooth ER could use additional information on its functions adding how the smooth ER lack ribosoms and why. This would be a good addition to the article. Also, Sarcoplasmic Reticulum was mentioned, which is undrelated to the organelle that is discussed in the opening paragraph. Omit this part of the article and draw more of a focus to that of the RER and SER which are the two key reticulums that are talked about in the opening paragraph.
Underneath the Functions portion of the article "Protein Transport" was all that was in bold. There are many more functions that occur within the ER that should be addressed such as: lipid metabolism in the membrane or even calcium storage.
Citations are also seemingly very limited in places throughout the article; the use of scholarly sources to help bring more and informing evidence to this article would be of great use. Truman15 (talk) 01:49, 29 September 2016 (UTC)
Cell Biology Review
The introduction of this article contains very useful information but there is also a lot of extraneous information that could be left out such as the sentence that says "Endoplasmic reticulum occurs in most types of eukaryotic cells, including Giardia, but is absent from red blood cells and spermatozoa". Also there should be a citation at the end of the introduction. I thought the history section of the article was very vague and could use some more information to help give a better background. The history section should also answer questions like when the discovery was published and accepted by the scientific community, and what type of eukaryotic cell the organelle was discovered in.
The function section of the article was well written and gave a good explanation of what the endoplasmic reticulum's main jobs are. There were some places that were very hard to follow and understand such as when it mentions the many different chaperone proteins. The rest of the information is very useful and easier to understand.
The citations for the article were very good sources and contained a lot of information for each section. Meaige4 (talk) 01:42, 30 September 2016 (UTC)
Cell Biology 322 Review
Although the article is brief, it assumes the reader has a higher understanding of biology—specifically intracellular mechanisms/processes—than most. For example, at the end of the "Structure of rough ER" section, the bullet points need attention. They are short and advanced. The average reader is not going to able to differentiate SNAP and SNARE proteins, as well as know the role they play. Either the information should be elaborated and/or should be placed in the "Function" section. Especially since the sentence preluding these bullet points states, "The rough endoplasmic reticulum is key in multiple functions..." I understand this is not ER functions, but bullet points will not do these processes justice if they are to stay in the article. In addition, the Function section should be revised and dumbed-down. For example, when the article references chaperone proteins it lists multiple proteins "including protein disulfide isomerase (PDI), ERp29, the Hsp70 family member BiP/Grp78, calnexin, calreticulin, and the peptidylpropyl isomerase family." This is not necessary. If the reader should want to know more about these proteins, an attached clickable link will suffice.
Regarding structure of the article, I noticed the ending sentence of the Introduction and the starting sentence of the History section are identical. Either the History section needs more data or the whole section should be added to the end of the Introduction. Also, the Sarcoplasmic reticulum subsection should be cut entirely, as there is little to no relevance, or perhaps shortened and mentioned in the Function section as an example. Tannerway (talk) 03:06, 30 September 2016 (UTC)
Cell Biology Class Review
I like that the history section includes the person that discovered the organelle and explains that the ER is considered to be a network. However, I feel that the section needs to be extended and that it should be elaborated to include the entire history from its discovery to present day. The remaining sections of the article pertaining to the function and types of ER contain a lot of jargon that isn't helpful to members of the community that are not studying science and can be stressful for one that would like to learn about this organelle. The article also discusses the organelle's significance in the animal cell, but does not elaborate very much on the minor differences in roles for plant cells. I enjoy the animation photo included in the article showcasing secretory pathways, but the image is not captioned properly and doesn't tell a person who is unfamiliar with the process what is going on. Finally, the 8th reference used in the article is not from a credible source, as anyone can post a response to answers.com and the answers are technically reviewed for accuracy. Riggs73 (talk) 05:25, 30 September 2016 (UTC)
Biology 322 Article Review
While this article is brief, it assumes that the reader has previous knowledge of intracellular biology, using overly complicated vocabulary that should be simplified into terms easier for the average reader to understand. A few sections where this complex terminology is shown would be the functions section where it discusses chaperone proteins and the protein transport section where it discussed KDEL and KKXX. I would recommend discussing these things further to provide better understanding and maybe adding links to other wikipedia pages to things such as hypoxia, ischemia, and insulin resistance, so if someone wants to read more about these things the information is readily available. Another issue I noticed was a lack in citations in many areas of the article where it was full of facts. Sources need to be cited so facts can be compared to the original works where they were found. Also, the format of the rough endoplasmic reticulum section seems a bit distracting. The bullet points are unnecessary and pulls the readers attention away from the article itself. Other than these things, I really enjoyed the article and was quite pleased with it, though I also would have liked to see more information in the sarcoplasmic and clinical significance sections of the articles. — Preceding unsigned comment added by Bshort97 (talk • contribs) 16:10, 30 September 2016 (UTC)
Biology 322 Review
When reviewing the introduction to the Endoplasmic Reticulum article, I found some of the information to be unnecessary or out of place. For instance, I don’t think that it was necessary to name specific cells (i.e. Giardia) as having an Endoplasmic Reticulum. I think that those details would be best placed elsewhere. Along with out of place details, some of the jargon used seems to be a little advanced for the average person. The paragraphs in the “Rough Endoplasmic Reticulum” are well explained. However, the bullet points underneath are filled with a lot of advanced terminology that is not further explained. The structure section is lacking the proper citation needed in order to justify the information provided. The eighth citation, which is in the “Rough Endoplasmic Reticulum” section, seems to be unreliable. The information is attributed to McGraw-Hill, however it says that it was retrieved from “answers.com.” There is also a citation missing from the first bullet point within the same section. Other than this, all of the provided citations seem to have functioning links.

smooth ER info about detox & steroid hormones & metabolism is OPPOSITE to what the cited place says (& incomplete citation text too?)
The second to last sentence in the lead says, "The smooth endoplasmic reticulum lacks ribosomes and functions in lipid synthesis but not metabolism, the production of steroid hormones, and detoxification." (italics by me), but following the given citation I find pretty much the opposite for the 3 actions mentioned after the word 'but' in the aforementioned lead sentence: "Smooth ER is devoted almost exclusively to the manufacture of lipids and in some cases to the metabolism of them and associated products." (bold added) And also, "Smooth ER is also involved in the production of steroid hormones in the adrenal cortex and endocrine glands."(bold added) And then, "Smooth ER also plays a large part in detoxifying a number of organic chemicals converting them to safer water-soluble products."(bold added)
So how does the presented information at the cited site justify the "NOT" in that lead sentence?
And while the citation does lead to the British Society for Cell Biology at https://bscb.org/learning-resources/softcell-e-learning/endoplasmic-reticulum-rough-and-smooth/ , the wording given to the citation is, " "Endoplasmic Reticulum (Rough and Smooth)". Archived from the original on 24 November 2015. Retrieved 21 November 2015. "(italics mine), which doesn't seem to indicate the BSCB as a source of information at all. Shouldn't it?

incorrect inline definition link
In the 'Functions' section, the inline definition link for endoplasmic reticulum stress response (ER stress) is for 'X-box binding protein 1' (XBP1). I ATTEMPTED to upload a screenshot of that -- but, this site refused to do the file upload, cryptically citing "The filename is not allowed" (w/ NO further explan!).
After opening the main Endoplasmic Reticulum article in a new tab of same browser window (Chrome), mousing over 'endoplasmic reticulum stress response' does not invoke an in-line definition. But clicking the 'endoplasmic reticulum stress response' hyperlink takes the viewer directly to the 'endoplasmic reticulum stress response' section in the 'X-box binding protein' article - thus establishing the link, even if not providing a succinct definition of 'ER stress'.
I suggest some modification of the in-line definition function for ER stress, to avoid appearance that that definition link is wrong.
- * * It would also be nice if the file upload function on Talk was more user-friendly -- the error msg "filename is not allowed" is of essentially NO help in resolving the issue, without indication of WHY the filename isn't allowed! (the moreso as the dis-allowed filename was selected within the upload file navigation function that interfaces between Wikipedia and my local machine!) Not being able to upload screenshot of a problematic situation, might (WILL!) dissuade page improvement suggestions by a conscientious visitor... * * *
