What pLDDT means and how to read it

Function

G protein-coupled receptor that plays key roles in the renin-angiotensin system (RAS) specifically in the protective, counter-regulatory arm of the RAS (PubMed:25967876). Receptor mainly stimulated by angiotensin 1-7, which is a bioactive metabolite of the angiotensin produced by ACE2 (PubMed:17984366). Activation promotes nitric oxide via PI3K/Akt-eNOS pathway (PubMed:17984366). Modulates also the MAPK, ERK1/2, and NF-kappa-B signaling (PubMed:25967876). Positive regulation of AGTR1 levels occurs through activation of the G proteins GNA11 and GNAQ, and stimulation of the protein kinase C signaling cascade (PubMed:15809376, PubMed:16611642). The antagonist effect on AGTR1 function is…

Subunit structure

Interacts with AGTR1. Interacts with FLNA (via filamin repeat 21); increases PKA-mediated phosphorylation of FLNA (PubMed:26460884)
