CC -!- FUNCTION: Catalyzes the conjugation of the 1'-hydroxyl group of D-myo-
CC inositol-3-phosphate (also named L-myo-inositol-1-phosphate) with a
CC lipid tail of cytidine diphosphate diacylglycerol (CDP-DAG), forming
CC phosphatidylinositol phosphate (PIP) and CMP. PIP is a precursor of
CC phosphatidylinositol (PI) which is an essential lipid required for cell
CC wall formation. {ECO:0000256|HAMAP-Rule:MF_02241}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=1,2-di-(9Z-octadecenoyl)-sn-glycero-3-cytidine-5'-diphosphate
CC + 1D-myo-inositol 3-phosphate = 1,2-di-(9Z-octadecenoyl)-sn-glycero-
CC 3-phospho-(1D-myo-inositol-3-phosphate) + CMP + H(+);

CC Rule:MF_02241};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=1D-myo-inositol 3-phosphate + a CDP-1,2-diacyl-sn-glycerol = a
CC 1,2-diacyl-sn-glycero-3-phospho-(1D-myo-inositol-3-phosphate) + CMP +
CC H(+); Xref=Rhea:RHEA:60504, ChEBI:CHEBI:15378, ChEBI:CHEBI:58088,

CC Rule:MF_02241};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_02241};
CC Note=Contains a di-nuclear catalytic Mg(2+) center. {ECO:0000256|HAMAP-
CC Rule:MF_02241};
CC -!- PATHWAY: Lipid metabolism. {ECO:0000256|ARBA:ARBA00005189}.
CC -!- PATHWAY: Phospholipid metabolism; phosphatidylinositol phosphate
CC biosynthesis. {ECO:0000256|ARBA:ARBA00004805, ECO:0000256|HAMAP-
CC Rule:MF_02241}.
CC -!- SUBUNIT: Homodimer. {ECO:0000256|ARBA:ARBA00011738, ECO:0000256|HAMAP-
CC Rule:MF_02241}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000256|HAMAP-Rule:MF_02241};
CC Multi-pass membrane protein {ECO:0000256|HAMAP-Rule:MF_02241}. Membrane
CC {ECO:0000256|ARBA:ARBA00004141}; Multi-pass membrane protein
CC {ECO:0000256|ARBA:ARBA00004141}.
CC -!- SIMILARITY: Belongs to the CDP-alcohol phosphatidyltransferase class-I
CC family. {ECO:0000256|ARBA:ARBA00010441, ECO:0000256|HAMAP-
CC Rule:MF_02241, ECO:0000256|RuleBase:RU003750}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_02241}.
