Anti-CHM antibodies are used in the immunodetection of the protein CHM Rab escort protein. In humans, the canonical protein has a reported length of 653 amino acid residues and a mass of 73.5 kDa. Its subcellular localization is in the cytoplasm. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the Rab GDI protein family, CHM is reported to be a substrate-binding subunit of the Rab geranylgeranyltransferase (GGTase) complex. The CHM gene has been associated with the disease, Choroideremia. Synonyms for this target antigen include GGTA, REP-1, TCD, rab proteins geranylgeranyltransferase component A 1, and DXS540. CHM gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of CHM antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
