Comment typeDescription
Catalytic ActivityCDP-choline + 1,2-diacyl-sn-glycerol = CMP + a phosphatidylcholine.
Catalytic ActivityCDP-ethanolamine + 1,2-diacyl-sn-glycerol = CMP + a phosphatidylethanolamine.
CofactorName=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence= ; Name=Mn(2+); Xref=ChEBI:CHEBI:29035; Evidence= ;
FunctionCatalyzes both phosphatidylcholine and phosphatidylethanolamine biosynthesis from CDP-choline and CDP- ethanolamine, respectively. Involved in protein-dependent process of phospholipid transport to distribute phosphatidyl choline to the lumenal surface. Has a higher cholinephosphotransferase activity than ethanolaminephosphotransferase activity (By similarity)
PathwayPhospholipid metabolism; phosphatidylcholine biosynthesis; phosphatidylcholine from phosphocholine: step 2/2.
PathwayPhospholipid metabolism; phosphatidylethanolamine biosynthesis; phosphatidylethanolamine from ethanolamine: step 3/3.
SimilarityBelongs to the CDP-alcohol phosphatidyltransferase class-I family
Subcellular LocationEndoplasmic reticulum membrane {ECO:0000250}; Multi-pass membrane protein . Nucleus membrane {ECO:0000250}; Multi-pass membrane protein .
