Anti-MAT/MATN1: Mouse MAT/MATN1 Antibody

BACKGROUND Methionine adenosyltransferase (MAT, ATP:L-methionine Sadenosyltransferase, EC catalyzes the biosynthesis of S-adenosylmethionine (AdoMet) from methionine and ATP and thus plays a central role in cellular metabolism. The the adenosyl moiety of ATP is transferred to methionine, forming a highly energetic compound as a result of a sulphonium bond between the 5’-carbon atom of the ribose and the sulphur atom of the amino acid. There are two isoenzymes of MAT: one is liver-specific and the other is present in all tissues. The first has a relatively high Km for methionine and the second has a low Km for methionine.1 AdoMet acts as the methyl donor for over 115 different cellular transmethylation reactions, including those of DNA, RNA, proteins, and lipids. DNA methylation is a important epigenetic feature of DNA that plays a critical role in gene expression and regulation. In addition, AdoMet participates in the transsulfuration pathway and, after decarboxylation, serves as a propylamine group donor in the biosynthesis of polyamines.2 Moreover, with the transfer of methyl group, AdoMet is converted into S-adenosylhomocysteine (AdoHcy). The majority of AdoMet-dependent methyltransferases are strongly inhibited by AdoHcy. The intracellular AdoMet/AdoHcy ratio has been used as a predictor of cellular methylation activity. AdoHcy is further converted into homocysteine and adenosine by the AdoHcy hydrolase, which is widely distributed in mammalian tissues. Hypercysteinaemia has been regarded as a new modifiable risk factor for atherosclerosis and vascular diseases.3
