Choline Phosphotransferase 1 (CHPT1)

CPT1; Phosphatidylcholine Synthesizing Enzyme; Cholinephosphotransferase 1; AAPT1-like protein; Diacylglycerol cholinephosphotransferase 1

Choline Phosphotransferase 1 (CHPT1)
Cholinephosphotransferase transfers a phosphocholine moiety from CDP-choline to diacylglycerol thus forming phosphatidylcholine (PtdCho) and CMP. This reaction defines the ultimate step in the Kennedy pathway for the genesis of de novo synthesized PtdCho.
CHPT1 belongs to the CDP-alcohol phosphatidyltransferase class-I family.Highly 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. Catalyzes phosphatidylcholine biosynthesis from CDP-choline. It thereby plays a central role in the formation and maintenance of vesicular membranes.
