Protein Structure

UniProt Annotation

Function

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. {ECO:0000269PubMed:10644686}.
