Protein attributes

Sequence length	292 AA.
Sequence status	Fragment.
Protein existence	Evidence at transcript level

General annotation (Comments)

Function	Catalyzes the methylation of glycine by using S-adenosylmethionine (AdoMet) to form N-methylglycine (sarcosine) with the concomitant production of S-adenosylhomocysteine (AdoHcy). Possible crucial role in the regulation of tissue concentration of AdoMet and of metabolism of methionine.
Catalytic activity	S-adenosyl-L-methionine + glycine = S-adenosyl-L-homocysteine + sarcosine.
Subunit structure	Homotetramer.
Subcellular location	Cytoplasm.
Tissue specificity	Abundant in liver.
Sequence similarities	Belongs to the glycine N-methyltransferase family.
