Anti-ARSL antibodies are used in the immunodetection of the protein arylsulfatase L. In humans, the canonical protein has a reported length of 589 amino acid residues and a mass of 65.7 kDa. Its subcellular localization is in the Golgi. It is reported to be expressed in the pancreas, liver and kidney. A member of the Sulfatase protein family, ARSL is known to be involved with skeletal system development. Post-translational modifications have been described, including N-glycosylation. The ARSL gene has been associated with the disease, Chondrodysplasia punctata. Synonyms for this target antigen include ASE, CDPX, CDPX1, CDPXR, arylsulfatase E (chondrodysplasia punctata 1), and ARSE. ARSL gene orthologs have been reported in the bovine and chimpanzee species.
