Immunogen A synthetic peptide from human Regulator of G-protein signaling 19 (RGS19) conjugated to an immunogenic carrier protein has been used as the antigen.
Specificity Specific for Optineurin.
Purification whole serum
Background G proteins mediate a number of cellular processes. The protein encoded by this gene belongs to the RGS (regulators of G-protein signaling) family and specifically interacts with G protein, GAI3. This protein is a guanosine triphosphatase-activating protein that functions to down-regulate Galpha i/Galpha q-linked signaling. Alternatively spliced transcript variants encoding the same protein isoform have been found for this gene.
Function: Inhibits signal transduction by increasing the GTPase activity of G protein alpha subunits thereby driving them into their inactive GDP-bound form. Binds to G-alpha subfamily 1 members, with the order G(i)a3 > G(i)a1 > G(o)a >> G(z)a/G(i)a2. Activity on G(z)-alpha is inhibited by phosphorylation and palmitoylation of the G-protein.
Subcellular location: Membrane, Lipid-anchor.
Tissue specificity: Highest expression in lung. Placenta, liver and heart also express high levels of GAIP. Also known as: RGS19, G-alpha-interacting protein, GAIP, GNAI3IP, RGSGAIP.
