Anti-GNAZ antibodies are used in the immunodetection of the protein G protein subunit alpha z. In humans, the canonical protein has a reported length of 355 amino acid residues and a mass of 40.9 kDa. Its subcellular localization is in the membrane. It is notably expressed in the gallbladder, colon, cerebral cortex, and cerebellum. A member of the G-alpha protein family, GNAZ is known to be involved with GPCR signaling pathways. Synonyms for this target antigen include gz-alpha, guanine nucleotide-binding protein G(z) subunit alpha, g(x) alpha chain, guanine nucleotide binding protein (G protein), alpha z polypeptide, and HG1H. GNAZ gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of GNAZ 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.
