MGI Phenotype FUNCTION: This gene encodes a member of the AdoMet synthase family. Methionine adenosyltransferase is a product of this gene (the alpha form) and the beta form and catalyzes the formation of S-adenosylmethionine from methionine and ATP.[provided by RefSeq, Jan 2013]
PHENOTYPE: Mice homozygous for disruptions in this gene have significantly elevated levels of methionine in the circulation and develop liver steatosis with age. [provided by MGI curators]
