Anti-CHM like Rab escort protein antibodies are used for the immunodetection of the protein encoded by the CHML gene. In humans, the canonical protein has a reported length of 656 amino acid residues and a mass of 74.1 kDa. Its subcellular localization is in the cytoplasm. A member of the Rab GDI protein family, it is known to be involved with intracellular protein transport and vesicle-mediated transport. Other names for this target antigen include rab proteins geranylgeranyltransferase component A 2, CHM like Rab escort protein 2, choroideraemia-like protein, choroideremia-like (Rab escort protein 2), choroideremia-like protein, and REP2. Gene orthologs have been identified in the mouse, rat, bovine and chimpanzee species.
