Comments
Comment typeDescription
Alternative ProductsEvent=Alternative splicing; Named isoforms=2; Name=1; Synonyms=Alpha; IsoId=Q8WUD6-1; Sequence=Displayed; Name=2; Synonyms=Beta; IsoId=Q8WUD6-2; Sequence=VSP_025989, VSP_025990;
Catalytic ActivityCDP-choline + 1,2-diacyl-sn-glycerol = CMP + a phosphatidylcholine.
CofactorName=Mg(2+); Xref=ChEBI
FunctionCatalyzes phosphatidylcholine biosynthesis from CDP- choline. It thereby plays a central role in the formation and maintenance of vesicular membranes.
PathwayPhospholipid metabolism; phosphatidylcholine biosynthesis; phosphatidylcholine from phosphocholine: step 2/2.
Sequence CautionSequence=AAD44019.1; Type=Frameshift; Positions=310; Evidence= ; Sequence=AAL39005.1; Type=Erroneous initiation; Evidence= ;
SimilarityBelongs to the CDP-alcohol phosphatidyltransferase class-I family.
Subcellular LocationGolgi apparatus membrane ; Multi-pass membrane protein .
Tissue SpecificityHighly expressed in testis, colon, small intestine, heart, prostate and spleen. Also detected in kidney, skeletal muscle, pancreas, leukocytes, ovary and thymus. Weakly expressed in the brain, placenta and lung. Overexpressed in cancerous breast epithelial cell lines.
