The role of PA in the cell can be divided into three categories: • PA is the precursor for the biosynthesis of many other lipids. • The physical properties of PA influence membrane curvature. • PA acts as a signaling lipid, recruiting cytosolic proteins to appropriate membranes (e.g., sphingosine kinase 1 ).

WebWhen phosphatidate phosphatase is inactive, diacylglycerol kinase catalyzes the reverse conversion, allowing phosphatidate to accumulate as it brings down diacylglycerol levels. Phosphatidate can then be converted into an activated form, CDP-diacylglycerol by liberation of a pyrophosphate from a CTP molecule, or into cardiolipin.
