Anti-GNAI2 antibodies are used in the immunodetection of the protein G protein subunit alpha i2. In humans, the canonical protein has a reported length of 355 amino acid residues and a mass of 40.5 kDa. Its subcellular localization is in the cell membrane and cytoplasm. Up to 6 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the G-alpha protein family, GNAI2 is known to be involved with GPCR signaling pathways and the cell cycle. Synonyms for this target antigen include GNAI2B, HG1C, H_LUCA15.1, H_LUCA16.1, guanine nucleotide-binding protein G(i) subunit alpha-2, and GIP. GNAI2 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of GNAI2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
