Anti-RGS3 Antibody Picoband® 0,00647 Vervoeging

RGS3 (Regulator of G Protein Signaling 3), is a protein that in humans is encoded by the RGS3 gene. Chatterjee et al. (1997) studied RGS3, the largest member of the RGS family then identified. Mouse Pdz-Rgs3 can mediate signaling from the ephrin-B cytoplasmic tail. By radiation hybrid mapping, Chatterjee et al. (1997) assigned the RGS3 gene to chromosome 9q31-q33. Lu et al. (2001) showed that Sdf1, a chemokine with a G protein-coupled receptor, and Bdnf are chemoattractants for cerebellar granule cells, and that Sdf1 chemoattraction is selectively inhibited by soluble ephrin-B receptor. This inhibition could be blocked by a truncated Pdz-Rgs3 protein lacking the RGS domain.

Rat, Mouse, Human

No cross-reactivity with other proteins

A synthetic peptide corresponding to a sequence at the C-terminus of mouse RGS3, identical to the related rat sequence, and different from the related human sequence by two amino acids.

Detected in embryos from E8.5-16.5 in cortical ventricular zone, dorsal root ganglia and cerebellar primordia. Isoform 3 is detected in testis and in spermatocytes from newborn mice. Levels increase and reach a maximum after 21 days; after this they decrease again. Long isoforms are widely expressed. .

Down-regulates signaling from heterotrimeric G-proteins by increasing the GTPase activity of the alpha subunits, thereby driving them into their inactive GDP-bound form. Down-regulates G- protein-mediated release of inositol phosphates and activation of MAP kinases. .
