Probable G-protein coupled receptor 75 is a protein that in humans is encoded by the GPR75 gene.[5][6]

Function

GPR75 is a member of the G protein-coupled receptor family. GPRs are cell surface receptors that activate guanine-nucleotide binding proteins upon the binding of a ligand.[6]

GPR75 is currently classified as an orphan GPCR and several studies are underway to identify its ligand. In one study, the chemokine CCL5 (RANTES) has been shown to stimulate calcium mobilization and inositol triphosphate formation in GPR75-transfected cells.[7]

Recently, 20-hydroxyeicosatetraenoic acid (20-HETE), a bioactive eicosanoid formed by ω-hydroxylation of arachidonic acid has been shown to mediate its prohypertensive effects on the vasculature through activation of GPR75 (Gq) signalling.[8] This study by Dr. Schwartzman's laboratory at New York Medical college, one of the pioneers in study of 20-HETE biology, has opened new insights into the field of GPR75 pharmacology.

gollark: Unrelatedly, it turns out that the large amount of 2-letter TLDs which exist now combined with the fact that 36^3 is a lot means that you can get 6-letter domains, and I mean 6 letter including the TLD and dot.

gollark: It also seems like a terrible protocol, design-wise.

gollark: I started actually doing backups instead of just having replicated copies of things recently, and I have something like 150GB of them.

gollark: The whole UPnP thing seems hilariously convoluted and bad and I don't know why they did it this way.

gollark: HTTPS is HTTP over TLS, it's not using HTTP as a lower level transport.
