At the inner mitochondrial (IM) membrane, phosphatidate cytidylyltransferase 2 (CDS2) converts phosphatidic acid (PA) and cytidine triphosphate (CTP) into cytidine diphosphate-diacylglycerol (CDP-DAG). Both ER and mitochondrial membranes have the capability to synthesise cytidine diphosphate-diacylglycerol (CDP-DAG) with phosphatidate cytidylyltransferase 1 and 2 (CDS1 and CDS2) (Lykidis et al. 1997, Schlame & Haldar 1993). However, transport of CDP-DAG between organelles cannot be ruled out (Stuhne-Sekalec et al. 1986).
