Anti-RALBP1 antibodies are used in the immunodetection of the protein ralA binding protein 1. In humans, the canonical protein has a reported length of 655 amino acid residues and a mass of 76.1 kDa. Its subcellular localization is in the cell membrane, nucleus, mitochondria, and cytoplasm. It is found to be widely expressed, but at low levels. RALBP1 is reported to be a multifunctional protein that functions as a downstream effector of RALA and RALB. Post-translational modifications have been described, including protein cleavage and phosphorylation. Synonyms for this target antigen include RLIP1, RLIP76, 76 kDa Ral-interacting protein, DNP-SG ATPase, dinitrophenyl S-glutathione ATPase, and RIP1.
