Background Information

Methionine adenosyltransferase (MAT) is the enzyme that catalyzes the synthesis of S-adeno-sylmethionine (AdoMet), the main donor of methyl groups in the cell. In mammals MAT is encoded by two different genes, MAT1A and MAT2A. MAT1A is expressed only in the mature liver whereas fetal hepatocytes, extrahepatic tissues and liver cancer cells express MAT2A. This antibody was raised against the full length of human MAT1A and may cross-react with MAT2A. Western blot analysis using this antibody detected a single band around 44-50 kDa in liver.
