背景介绍
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. [provided by RefSeq, Sep 2011],
组织表达
Isoform 5 is expressed in brain at high levels in the caudate nucleus and temporal lobe.
细胞定位
Membrane; Lipid-anchor. Nucleus. Cytoplasm. Shuttles between the cytoplasm/cell membrane and the nucleus. Anchored to the membrane through palmitoylation. .
功能
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.,PTM:Fatty acylated. Heavily palmitoylated in the cysteine string motif.,PTM:N- and O-glycosylated in synapsomal membranes.,PTM:Serine phosphorylated in synapsomal membranes.,PTM:Sumoylated by SUMO1 and SUM02 in synaptosomes. The sumoylated forms act as a scaffold for sequestering mu-opioid receptor-activated G(alpha) subunits.,similarity:Contains 1 RGS domain.,subcellular location:Shuttles between the cytoplasm/cell membrane and the nucleus (By similarity). Anchored to the membrane through palmitoylation.,subunit:Forms a complex with G(alpha)z/i2 subunits and mu-opioid receptors; the formation of this complex results in mu-opioid receptor desensitization. Interacts with OPRM1.,tissue specificity:In the brain, isoform 5 is expressed at high levels in the caudate nucleus and temporal lobe.,
纯化
The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen.
