Rabbit Anti-RGS20/FITC Conjugated antibody
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. [provided by RefSeq, Sep 2011]
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.
Subcellular Location:
Membrane. Nucleus. Cytoplasm. Shuttles between the cytoplasm/cell membrane and the nucleus (By similarity). Anchored to the membrane through palmitoylation.
Tissue Specificity:
Isoform 5 is expressed in brain at high levels in the caudate nucleus and temporal lobe.
Post-translational modifications:
Fatty acylated. Heavily palmitoylated in the cysteine string motif.
N- and O-glycosylated in synapsomal membranes.
Serine phosphorylated in synapsomal membranes.
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.
