Summaries for MAT2B Gene

Entrez Gene Summary for MAT2B Gene

  • The protein encoded by this gene belongs to the methionine adenosyltransferase (MAT) family. MAT catalyzes the biosynthesis of S-adenosylmethionine from methionine and ATP. This protein is the regulatory beta subunit of MAT. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Nov 2012]

GeneCards Summary for MAT2B Gene

MAT2B (Methionine Adenosyltransferase II, Beta) is a Protein Coding gene. Among its related pathways are Metabolism and Carbon metabolism. GO annotations related to this gene include dTDP-4-dehydrorhamnose reductase activity and methionine adenosyltransferase regulator activity.

UniProtKB/Swiss-Prot for MAT2B Gene

  • Non-catalytic regulatory subunit of S-adenosylmethionine synthetase 2 (MAT2A), an enzyme that catalyzes the formation of S-adenosylmethionine from methionine and ATP. Regulates the activity of S-adenosylmethionine synthetase 2 by changing its kinetic properties, rendering the enzyme more susceptible to S-adenosylmethionine inhibition.
