Protein Function One of the isoforms of the enzyme Serine hydroxymethyltransferase (SHMT),which catalyzes the reversible conversion of l-serine and tetrahydrofolate into glycine and 5,10-methylenetetrahydrofolate. This enzyme, which plays a pivotal role in one-carbon metabolism, is involved in cancer metabolic reprogramming and is a recognized target of chemotherapy intervention. 
PTMs N6-acetylation at Lysine,Phosphorylation at Serine,Succinylation
Site(s) of PTM(s)

N-glycosylation, O-glycosylation,
Phosphorylation
NA
Predicted Disorder Regions NA
DisProt Annotation
