Anti-Transducin alpha antibodies enable researchers to detect and measure the Transducin alpha antigen in biological samples. This target is a reported synonym of the GNAZ gene, which encodes G protein subunit alpha z. This protein is known to function in GPCR signaling pathways, among other biological roles. The human version of Transducin alpha has a canonical amino acid length of 355 residues and a protein mass of 40.9 kilodaltons. It is reported to be localized in the membrane of cells and notably expressed in the gallbladder, colon, cerebral cortex, and cerebellum. Transducin alpha is a member of the G-alpha protein family.
