Anti-GRK3 antibodies are used in the immunodetection of the protein G protein-coupled receptor kinase 3. In humans, the canonical protein has a reported length of 688 amino acid residues and a mass of 79.7 kDa. A member of the AGC Ser/Thr protein kinase protein family, GRK3 is known to be involved with GPCR signaling pathways and protein phosphorylation. Post-translational modifications have been described, including ubiquitination. Synonyms for this target antigen include BARK2, beta-adrenergic receptor kinase 2, adrenergic, beta, receptor kinase 2, beta-ARK-2, and ADRBK2. GRK3 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of GRK3 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
