Gene information for MAT1A (Homo sapiens)
(Information is obtained from NCBI Gene database)
Entrez gene ID4143
Official gene symbolMAT1A
Full namemethionine adenosyltransferase I, alpha
Aliases,MAT,MATA1,SAMS,SAMS1,
Gene summaryThis 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]
