Previous GeneCards Identifiers for MAT1A Gene
This gene catalyzes a two-step reaction that involves the transfer of the adenosyl moiety of ATP to methionine to form S-adenosylmethionine and tripolyphosphate, which is subsequently cleaved to PPi and Pi. S-adenosylmethionine is the source of methyl groups for most biological methylations. The encoded protein is found as a homotetramer (MAT I) or a homodimer (MAT III) whereas a third form, MAT II (gamma), is encoded by the MAT2A gene. Mutations in this gene are associated with methionine adenosyltransferase deficiency. [provided by RefSeq, Jul 2008]
GeneCards Summary for MAT1A Gene
MAT1A (Methionine Adenosyltransferase 1A) is a Protein Coding gene. Diseases associated with MAT1A include Hypermethioninemia, Persistent, Autosomal Dominant, Due To Methionine Adenosyltransferase I/Iii Deficiency and Hypermethioninemia With Deficiency Of S-Adenosylhomocysteine Hydrolase. 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 MAT2A.
UniProtKB/Swiss-Prot for MAT1A 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.
