Anti-CRLS1 antibodies are used in the immunodetection of the protein cardiolipin synthase 1. In humans, the canonical protein has a reported length of 301 amino acid residues and a mass of 32.6 kDa. Its subcellular localization is in the mitochondria. Up to 2 different isoforms have been reported for this protein. It is reported to be highly expressed in tissues such as heart, skeletal muscle and liver. A member of the CDP-alcohol phosphatidyltransferase class-I protein family, CRLS1 is known to catalyze the synthesis of cardiolipin (CL) (diphosphatidylglycerol) by specifically transferring a phosphatidyl group from CDP-diacylglycerol to phosphatidylglycerol (PG). Synonyms for this target antigen include C20orf155 and CLS. CRLS1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of CRLS1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
