Comment typeDescription
Catalytic ActivityCDP-diacylglycerol + myo-inositol = CMP + phosphatidyl-1D-myo-inositol.
CofactorName=Mn(2+); Xref=ChEBI:CHEBI:29035; Evidence={ECO:0000250}; Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000250}; Note=Divalent metal cations; Mn(2+) or Mg(2+), but Mg(2+) may be much less effective. {ECO:0000250};
FunctionCatalyzes the biosynthesis of phosphatidylinositol (PtdIns) as well as PtdIns:inositol exchange reaction. May thus act to reduce an excessive cellular PtdIns content. The exchange activity is due to the reverse reaction of PtdIns synthase and is dependent on CMP, which is tightly bound to the enzyme (By similarity). {ECO:0000250}.
SimilarityBelongs to the CDP-alcohol phosphatidyltransferase class-I family. {ECO:0000305}.
Subcellular LocationEndoplasmic reticulum membrane {ECO:0000250}; Multi-pass membrane protein {ECO:0000250}. Golgi apparatus membrane {ECO:0000250}; Multi-pass membrane protein {ECO:0000250}. Cell membrane {ECO:0000250}; Multi-pass membrane protein {ECO:0000250}. Membrane {ECO:0000250}.
