Talk:Receptor (biochemistry)

message: Hmmm...  How come this page about Receptors is under 'Proteomics' ?
How about 'Cell Biology' or 'Pharmacology' ? - PFHLai 14:11, 2004 May 18 (UTC)
I concur. Although receptors are mainly proteins, not all are. This article should be moved and edited to correct this. - Centrx 21:59, 19 May 2004 (UTC)

message: The word cognate is often used in conjunction with receptors and ligands; the word should appear in this article and be defined.  — Preceding unsigned comment added by Tedtoal (talk • contribs) 17:57, 19 April 2018 (UTC)

message: If you look at receptor, it has many incoming links, almost all meant for this article. I propose this article is moved to receptor, and the disambiguation page moved to receptor (disambiguation), with a link to that placed at the top of (the new) receptor. ssepp(talk) 21:24, 18 May 2007 (UTC)

thread_title:  Toll-like receptors ? 

message: I think the term receptor refers to two separate concepts in biochemistry and these should be covered in separate articles to avoid confusion. 
# signal transduction receptor is a protein involved in converting an extracellular signal to an intracellular signal.  The extracellular signal can be a molecule (neurotransmitter, hormone, antigen, etc.) or a physical stimuli (light, electric field, physical deformation due to touch, sound, etc.). The signal can be relayed in terms of opening a channel, activating a kinase, binding to DNA, etc. So this category includes neurotransmitter receptors, nuclear hormone receptors, photoreceptors, etc.
# attachment receptor is a molecule (not necessarily a protein) that enables specific binding of a ligand to a cell. Examples would be viral receptors (e.g. the lamB porin for lambda phage or CD4 for HIV), endocytic receptors (eg. LDL receptor for LDL, sialic acid for influenza virus and ganglioside GM1 for cholera toxin), and cell adhesion receptors (N-CAM for nerve cells binding each other, adhesins receptors mediating binding of bacteria to epithelial cells).
This distinction should be made in the disambiguation page for receptor and two separate articles should cover these topics broadly.

thread_title:  two senses of receptor 

message: The equation L.R <--> LR is wrong.
It should be
L + R <-->  LR
      
In other words, the sign should be + not "." 
And the constant corresponds to Ka, not to Kd  (the reaction as it is shown correspond to an association, not to a dissociation).
The reverse equation corresponds to Kd and Ka = 1/Kd  —Preceding unsigned comment added by 200.16.86.36 (talk) 13:56, 19 October 2009 (UTC)

message: I've added a couple of sentences at the top of the page in plain English, in response to the request to de-jargon it. Hope that's OK KatArney (talk) 12:57, 4 May 2011 (UTC)

thread_title:  Plain English at top 

message: The section on receptor desensitization, under Receptor Regulation, has two bullet points:     
:* Uncoupling of receptor effector molecules.
:* Receptor sequestration (internalization).
These need to be explained or linked to explanatory pages. Also it would be helpful to know how these relate to Receptor Regulation. Based on a quick google search, I'm guessing they may refer to two types of desensitization (I only saw these mentioned in an article about one type of receptor and the passage referring to the two mechanisms was unclear about weather or not this information was specific to the receptor discussed in the article.) Anyway, if someone has access to the book cited with these bullet points or knows of another source that generally explains what they mean and how they relate to receptor regulation, it would be great if they could elaborate here.  — --Xttina.Garnet (talk) 11:18, 10 June 2011 (UTC)
replies: text: Yes, that's a good point. I've tried to fix it, at least to the point of providing internal links. Does that help? --Tryptofish (talk) 19:02, 10 June 2011 (UTC)

Cells can increase (upregulate) or decrease (downregulate) the number of receptors to a given hormone or neurotransmitter to alter their sensitivity to different molecule? (add s, and shouldn't "to a given hormone or neurotransmitter" just be "for a given ligand"?)
This is a locally acting feedback mechanism - Change "is" to "can be" and add - between locally & acting
