Anti-GAB2 antibodies are used in the immunodetection of the protein GRB2 associated binding protein 2. In humans, the canonical protein has a reported length of 676 amino acid residues and a mass of 74.5 kDa. Its subcellular localization is in the cell membrane and cytoplasm. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the GAB protein family, GAB2 is reported to be an adapter protein, which acts downstream of several membrane receptors including cytokine, antigen, hormone, cell matrix and growth factor receptors to regulate multiple signaling pathways. Synonyms for this target antigen include growth factor receptor bound protein 2-associated protein 2, pp100, and Grb2-associated binder 2. GAB2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of GAB2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
