Anti-RALGAPA2 antibodies are used in the immunodetection of the protein Ral GTPase activating protein catalytic subunit alpha 2. In humans, the canonical protein has a reported length of 1873 amino acid residues and a mass of 210.8 kDa. Its subcellular localization is in the cytoplasm. Up to 3 different isoforms have been reported for this protein. RALGAPA2 is a known catalytic subunit of the heterodimeric RalGAP2 complex which acts as a GTPase activator for the Ras-like small GTPases RALA and RALB. Synonyms for this target antigen include 250 kDa substrate of Akt, Ral GTPase activating protein catalytic alpha subunit 2, Ral GTPase activating protein, alpha subunit 2 (catalytic), and ral GTPase-activating protein subunit alpha-2. RALGAPA2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Immunofluorescence is the most common application for the RALGAPA2 antibodies listed below. ELISA, Western Blot, Immunocytochemistry, and Immunohistochemistry are also common applications.
