CC   -!- FUNCTION: Catalyzes the conversion of phosphatidic acid (PA) to CDP-
CC       diacylglycerol (CDP-DAG), an essential intermediate in the synthesis of
CC       phosphatidylglycerol, cardiolipin and phosphatidylinositol
CC       (PubMed:29253589). Exhibits specificity for the nature of the acyl
CC       chains at the sn-1 and sn-2 positions in the substrate, PA and the
CC       preferred acyl chain composition is 1-stearoyl-2-arachidonoyl-sn-
CC       phosphatidic acid (By similarity). Plays an important role in
CC       regulating the growth and maturation of lipid droplets which are
CC       storage organelles at the center of lipid and energy homeostasis (By
CC       similarity). {ECO:0000250|UniProtKB:O95674,
