Anti-GAB1 antibodies are used in the immunodetection of the protein GRB2 associated binding protein 1. In humans, the canonical protein has a reported length of 694 amino acid residues and a mass of 76.6 kDa. 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, GAB1 is a reported adaptor protein that plays a role in intracellular signaling cascades triggered by activated receptor-type kinases. Synonyms for this target antigen include GRB2-associated binder 1, deafness, autosomal recessive 26, growth factor receptor bound protein 2-associated protein 1, symbol withdrawn, see GAB1, and DFNB26. GAB1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 130 citations in the literature describe the use of GAB1 antibodies in research. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
