Protein attributes

Sequence length	292 AA.
Sequence status	Fragment.
Sequence processing	The displayed sequence is not processed.
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 By similarity.
Catalytic activity	S-adenosyl-L-methionine + glycine = S-adenosyl-L-homocysteine + sarcosine.
Subunit structure	Homotetramer.
Subcellular location	Cytoplasm.
Tissue specificity	Abundant in liver.
