Anti-GAMT antibodies are used in the immunodetection of the protein guanidinoacetate N-methyltransferase. In humans, the canonical protein has a reported length of 236 amino acid residues and a mass of 26.3 kDa. Up to 2 different isoforms have been reported for this protein. It is notably expressed in the liver. A member of the RMT2 methyltransferase protein family, GAMT is known to be involved with organ morphogenesis and spermatogenesis. The GAMT gene has been associated with the disease, Cerebral creatine deficiency syndrome. Synonyms for this target antigen include HEL-S-20, PIG2, TP53I2, epididymis secretory protein Li 20, and CCDS2. GAMT gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of GAMT 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.
