Gene Gene information from NCBI Gene database.
Entrez ID 4143
Gene name Methionine adenosyltransferase 1A
Gene symbol MAT1A
Synonyms (NCBI Gene)
MATMATA1SAMSSAMS1
Chromosome 10
Chromosome location 10q22.3
Summary 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 gro
