FAMILY

ADOMET synthetase family

CATEGORY

enzyme

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm,cytosolic

basic FUNCTION	catalyzes the production of S-adenosylmethionine from methionine and ATP, which plays a pivotal role in the methylation of neurotransmitters, DNA, proteins, and lipids
	catalyzes the transfer of the adenosyl moiety from ATP to L-methionine to synthesize S-adenosylmethionine (SAM)

CELLULAR PROCESS

PHYSIOLOGICAL PROCESS

PATHWAY

INTERACTION

DNA

RNA

small molecule	cofactor,
	binds 2 divalent ions per subunit, magnesium or cobalt
	binds 1 potassium ion per subunit

protein	transcription factor SP1 seems to play a decisive role in MAT2A induction, as it binds the promoter when the gene is being actively transcribed (
	serves as a transcriptional corepressor of MAF oncoprotein
	interacts with histone methyltransferase SETDB1 and inhibits PTGS2 gene expression

cell & other

REGULATION

Other	phosphorylation of MAT2A, MAT2B proteins during hepatic stellate cells (HSCs) activation stabilizes them thereby positively regulating trans-differentiation
	its enzymatic activity is regulated by an associated subunit MAT2B

ASSOCIATED DISORDERS

Susceptibility

to familial thoracic aortic aneurysms and dissections (FTAAD)

Variant & Polymorphism other	MAT2A mutations are a rare cause of FTAAD
