Anti-RALGAPB antibodies are used in the immunodetection of the protein Ral GTPase activating protein non-catalytic subunit beta. In humans, the canonical protein has a reported length of 1494 amino acid residues and a mass of 166.8 kDa. Up to 4 different isoforms have been reported for this protein. It is reported to be highly expressed in the brain, mostly in amygdala. RALGAPB is reported to be a non-catalytic subunit of the heterodimeric RalGAP1 and RalGAP2 complexes which act as GTPase activators for the Ras-like small GTPases RALA and RALB. Synonyms for this target antigen include Ral GTPase activating protein non-catalytic beta subunit, Ral GTPase activating protein, beta subunit (non-catalytic), and ral GTPase-activating protein subunit beta. RALGAPB gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Immunocytochemistry is the most common application for the RALGAPB antibodies listed below. Immunofluorescence and Immunohistochemistry are also common applications.
