Summary
CDS1 (CDP-diacylglycerol synthase 1, HGNC:1800) is a protein-coding gene on chromosome 4q21.23, encoding Phosphatidate cytidylyltransferase 1 (Q92903). Catalyzes the conversion of phosphatidic acid (PA) to CDP-diacylglycerol (CDP-DAG), an essential intermediate in the synthesis of phosphatidylglycerol, cardiolipin and phosphatidylinositol.
Breakdown products of phosphoinositides are ubiquitous second messengers that function downstream of many G protein-coupled receptors and tyrosine kinases regulating cell growth, calcium metabolism, and protein kinase C activity. This gene encodes an enzyme which regulates the amount of phosphatidylinositol available for signaling by catalyzing the conversion of phosphatidic acid to CDP-diacylglycerol. This enzyme is an integral membrane protein localized to two subcellular domains, the matrix side of the inner mitochondrial membrane where it is thought to be involved in the synthesis of phosphatidylglycerol and cardiolipin and the cytoplasmic side of the endoplasmic reticulum where it functions in phosphatidylinositol biosynthesis. Two genes encoding this enzyme have been identified in humans, one mapping to human chromosome 4q21 and a second to 20p13.

UniProt curated annotations — full annotation on UniProt →
Function. Catalyzes the conversion of phosphatidic acid (PA) to CDP-diacylglycerol (CDP-DAG), an essential intermediate in the synthesis of phosphatidylglycerol, cardiolipin and phosphatidylinositol. Exhibits almost no acyl chain preference for PA, showing no discrimination for the sn-1/sn-2 acyl chain composition of PAs. Plays an important role in regulating the growth of lipid droplets which are storage organelles at the center of lipid and energy homeostasis. Positively regulates the differentiation and development of adipocytes.
Subunit / interactions. Homodimer. Interacts with FOS; this interaction may enhance catalytic activity.
Subcellular location. Endoplasmic reticulum membrane.
Tissue specificity. Expressed in adult tissues such as placenta, brain, small intestine, ovary, testis and prostate. Highly expressed in fetal kidney, lung and brain. Lower level in fetal liver.
Activity regulation. Inhibited by its anionic phospholipid end products, with phosphatidylinositol-(4,5)- bisphosphate showing the strongest inhibition.
Pathway. Phospholipid metabolism; CDP-diacylglycerol biosynthesis; CDP-diacylglycerol from sn-glycerol 3-phosphate: step 3/3.
Similarity. Belongs to the CDS family.

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 77 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
