Gene Summary
CDP-diacylglycerol synthase (Cds) encodes an enzyme for the synthesis of cytidine diphosphate diacylglycerol (CDP-DAG) from phosphatidic acid. CDP-DAG is the precursor of two phospholipids, phosphatidylinositol and phosphatidylglycerol. The product of Cds has roles in cell growth and lipid storage.

Gene Group (FlyBase)
CYTIDYLYLTRANSFERASES -
Cytidylyltransferases catalyse the transfer of a cytidylyl group to an acceptor.
Protein Function (UniProtKB)
Catalyzes the conversion of phosphatidic acid (PA) to CDP-diacylglycerol (CDP-DAG), an important precursor for the synthesis of phosphatidylinositol (PtdIns) and phosphatidylglycerol (PG) (PubMed:24603715, PubMed:7816135). Required for the regeneration of the signaling molecule phosphatidylinositol 4,5-bisphosphate (PtdInsP2) from PA and maintenance of its steady supply during signaling thus playing an essential role during phospholipase C-mediated transduction (PubMed:7816135). In the salivary glands and possibly other adipose tissues, function is essential for regulating cell growth and neutral lipid storage by coordinating PtdIns metabolism and insulin pathway activity (PubMed:24603715). Acts by positively regulating activity of the insulin pathway through synthesis of PtdIns, and in turn the insulin pathway up-regulates the synthesis of CdsA (PubMed:24603715). This CdsA-insulin positive feedback loop may be one of the mechanisms for coordinating cell growth and fat storage; switching to fat storage when cells reach homeostasis or converting from growth to fat storage under nutrient-poor conditions (PubMed:24603715). Required for spermatid individualization by regulating lipid compositions and lipid-mediated signaling during spermatogenesis (PubMed:26791243).

        CdsA diverts phosphatidic acid from triacylglycerol synthesis to phosphatidylinositol synthesis and coordinates cell growth and fat storage.

        May be required for tracheal terminal cell growth and branching.

        A step in the resynthesis of phosphatidylinositol-4,5-biphosphate, PtdInsP2 (needed for signal transduction), is performed by CDP-DAG synthase. CdsA encodes CDP-DAG synthase, an enzyme that activates phosphatidic acid by converting it to CDP-DAG.

        CdsA protein is required for the regeneration of the signalling molecule phosphatidylinositol-4,5-biphosphate (PtdInsP2) from phosphatidic acid. A photoreceptor cell isoform of CdsA is a key regulator of phototransduction.
