Anti-MATA1 antibodies enable researchers to detect and measure the MATA1 antigen in biological samples. This target is a reported synonym of the MAT1A gene, which encodes methionine adenosyltransferase 1A. This protein is known to function in metabolic processes, among other biological roles. The human version of MATA1 has a canonical amino acid length of 395 residues and a protein mass of 43.6 kilodaltons. It is reported to be notably expressed in the liver. Other names for this target antigen include MAT and SAMS.
