Scientific Background: PCYT1A is the rate limiting enzyme in the biosynthetic pathway for phosphatidylcholine. It catalyzes the reaction: CTP + phosphocholine = diphosphate + CDP-choline. It is an ambiquitous enzyme that resides in the cytoplasm of cells in an inactive form. Diacylglycerol, acidic phospholipids and fatty acids drive the binding of PCYT1A to the endoplasmic reticulum and stimulation of its catalytic activity.
