Anti-GAMT Antibody Picoband®

Guanidinoacetate N-methyltransferase (EC 2.1.1.2) is an enzyme that catalyzes the chemical reaction and is encoded by gene GAMT located on chromosome 19p13.3. The protein encoded by this gene is a methyltransferase that converts guanidoacetate to creatine, using S-adenosylmethionine as the methyl donor. Defects in this gene have been implicated in neurologic syndromes and muscular hypotonia, probably due to creatine deficiency and accumulation of guanidinoacetate in the brain of affected individuals. Two transcript variants encoding different isoforms have been described for this gene. Pseudogenes of this gene are found on chromosomes 2 and 13.

E.coli-derived human GAMT recombinant protein (Position: M1-G236) . Human GAMT shares 88.1% and 86.8% amino acid (aa) sequence identity with mouse and rat GAMT.
