Recombinant Human Regulator of G-protein signaling 20 (RGS20)

Uniprot Id

O76081

Target Species

Human

Target Name

RGS20

Target Full Name

Regulator of G-protein signaling 20

Target Function

Inhibits signal transduction by increasing the GTPase activity of G protein alpha subunits thereby driving them into their inactive GDP-bound form. Binds selectively to G(z)-alpha and G(alpha)-i2 subunits, accelerates their GTPase activity and regulates their signaling activities. The G(z)-alpha activity is inhibited by the phosphorylation and palmitoylation of the G-protein. Negatively regulates mu-opioid receptor-mediated activation of the G-proteins.

Target Subcellular Location

Membrane; Lipid-anchor. Nucleus. Cytoplasm.

Target Tissue Specificity

Isoform 5 is expressed in brain at high levels in the caudate nucleus and temporal lobe.

Target Background

The protein encoded by this gene belongs to the family of regulator of G protein signaling (RGS) proteins, which are regulatory and structural components of G protein-coupled receptor complexes. RGS proteins inhibit signal transduction by increasing the GTPase activity of G protein alpha subunits, thereby driving them into their inactive GDP-bound forms. This protein selectively binds to G(z)-alpha and G(alpha)-i2 subunits, and regulates their signaling activities. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.
