CC -!- FUNCTION: Controls phosphatidylcholine synthesis. CC -!- CATALYTIC ACTIVITY: CTP + choline phosphate = diphosphate + CDP- CC choline. CC -!- ENZYME REGULATION: By phosphorylation (By similarity). CC -!- SUBUNIT: Homodimer (By similarity). CC -!- SUBCELLULAR LOCATION: It can interconvert between an inactive CC cytosolic form and an active membrane-bound form (By similarity). CC -!- PTM: The serine residues of the C-terminus are phosphorylated. The CC inactive soluble form is stabilized by phosphorylation, the active CC membrane bound form is promoted by anionic lipids or CC diacylglycerol, and is stabilized by dephosphorylation (By CC similarity). CC -!- SIMILARITY: Belongs to the cytidylyltransferase family.
