Merger Proposal

The following discussion is closed. Please do not modify it. Subsequent comments should be made in a new section. A summary of the conclusions reached follows.

Closing this discussion due to it being placed on the wrong page per WP:MERGE; merge discussions for redirects should be placed on the the talk page of the destination page, not the talk page of the article that is proposed to become the redirect. This discussion will not be reopened on G protein due to a new discussion to merge Heterotrimeric G protein to G protein-coupled receptor. For that discussion, please go here. Thank you.

If there are no objections, I would merge content of this page to G protein and make this page redirect. Biophys (talk) 16:27, 17 June 2011 (UTC)[reply]

Gustducin

Gustducin has been shown to act through a GPCR-Gq/Gβγ-IP3 pathway and a GPCRGs-cAMP pathway (promoting the activity of adenylyl cyclase) in taste transduction. See here: Gustducin#Gustducin_and_its_second_messengers

There is also some information here: Gustducin#Comparisons_with_transducin "Similarly, α-gustducin binds the inhibitory units subunits of taste cell camp PDE which also causes a decrease in cAMP levels."

Not sure how we can elucidate all this information. — Preceding unsigned comment added by HeavyQuark (talk • contribs) 19:54, 11 December 2012 (UTC)[reply]

G protein families pages

The information shown here about the 4 G protein families is correct. However the pages that show up when you click a link that should lead to a wiki page about the family, they are about only some of the G proteins and not about all family members. For example the page for Gi does not include subunits t1-3 and z. The only page that does include all family members is Gq.
I think that maybe these pages should be renamed (e.g. Gq alpha subunit → Gq/11 alpha family) and should include all members.

Image description

In the image, described as "This heterotrimeric G protein is illustrated with its theoretical lipid anchors. GDP is black. Alpha chain is yellow. Beta and gamma chains are blue."

The black part is not immediately seen. I'd modify to

   "GDP is black, wrapped in the yellow alpha chain, at the bottom right side of the picture"

and I'd say at the beginning what is the grey part (because is bigger, that's why I'd say it as first thing), but I don't know what it is so I can't write it. What do you think? 😃 — Preceding unsigned comment added by 131.181.167.16 (talk) 06:26, 24 February 2020 (UTC)[reply]

sentence incorrect

"G proteins are made up of alpha (α), beta (β) and gamma (γ) subunits." This neglects that some G proteins only have subunit. CaffeineWitcher (talk) 06:58, 9 May 2020 (UTC)[reply]
