Summaries for MAT2A Gene

Entrez Gene Summary for MAT2A Gene

  • The protein encoded by this gene catalyzes the production of S-adenosylmethionine (AdoMet) from methionine and ATP. AdoMet is the key methyl donor in cellular processes. [provided by RefSeq, Jun 2011]

GeneCards Summary for MAT2A Gene

MAT2A (Methionine Adenosyltransferase 2A) is a Protein Coding gene. Diseases associated with MAT2A include Acute Maxillary Sinusitis and Glycine N-Methyltransferase Deficiency. Among its related pathways are Metabolism and Cytochrome P450 - arranged by substrate type. GO annotations related to this gene include methionine adenosyltransferase activity. An important paralog of this gene is MAT1A.

UniProtKB/Swiss-Prot for MAT2A Gene

  • Catalyzes the formation of S-adenosylmethionine from methionine and ATP. The reaction comprises two steps that are both catalyzed by the same enzyme: formation of S-adenosylmethionine (AdoMet) and triphosphate, and subsequent hydrolysis of the triphosphate.
