Use at an assay dependent dilution.
機能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.
組織特異性Isoform 5 is expressed in brain at high levels in the caudate nucleus and temporal lobe.
配列類似性Contains 1 RGS domain.
翻訳後修飾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.
細胞内局在Membrane. Nucleus. Cytoplasm. Shuttles between the cytoplasm/cell membrane and the nucleus (By similarity). Anchored to the membrane through palmitoylation.
