Regulator of G protein signaling 4 also known as RGP4 is a protein that in humans is encoded by the RGS4 gene. RGP4 regulates G protein signaling.
Regulator of G-protein signaling 2 is a protein that in humans is encoded by the RGS2 gene. It is part of a larger family of RGS proteins that control signalling through G-protein coupled receptors (GPCR).
Guanine nucleotide-binding protein G(q) subunit alpha is a protein that in humans is encoded by the GNAQ gene. Together with GNA11, it functions as a Gq alpha subunit.
Guanine nucleotide-binding protein G(i), alpha-1 subunit is a protein that in humans is encoded by the GNAI1 gene.
Regulators of G protein signaling (RGS) are protein structural domains or the proteins that contain these domains, that function to activate the GTPase activity of heterotrimeric G-protein α-subunits.
GIPC PDZ domain containing family, member 1 (GIPC1) is a protein that in humans is encoded by the GIPC1 gene. GIPC was originally identified as it binds specifically to the C terminus of RGS-GAIP, a protein involved in the regulation of G protein signaling. GIPC is an acronym for "GAIP Interacting Protein C-terminus". RGS proteins are "Regulators of G protein Signaling" and RGS-GAIP is a "GTPase Activator protein for Gαi/Gαq", which are two major subtypes of Gα proteins. The human GIPC1 molecule is 333 amino acids or about 36 kDa in molecular size and consists of a central PDZ domain, a compact protein module which mediates specific protein-protein interactions. The RGS-GAIP protein interacts with this domain and many other proteins interact here or at other parts of the GIPC1 molecule. As a result, GIPC1 was independently discovered by several other groups and has a variety of alternate names, including synectin, C19orf3, RGS19IP1 and others. The GIPC1 gene family in mammals consisting of three members, so the first discovered, originally named GIPC, is now generally called GIPC1, with the other two being named GIPC2 and GIPC3. The three human proteins are about 60% identical in protein sequence. GIPC1 has been shown to interact with a variety of other receptor and cytoskeletal proteins including the GLUT1 receptor, ACTN1, KIF1B, MYO6, PLEKHG5, SDC4/syndecan-4, SEMA4C/semaphorin-4 and HTLV-I Tax. The general function of GIPC family proteins therefore appears to be mediating specific interactions between proteins involved in G protein signaling and membrane translocation.
