Anti-CDS1 antibodies are used in the immunodetection of the protein CDP-diacylglycerol synthase 1. In humans, the canonical protein has a reported length of 461 amino acid residues and a mass of 53.3 kDa. Its subcellular localization is in the ER. It is reported to be expressed in adult tissues such as placenta, brain, small intestine, ovary, testis and prostate. A member of a the CDS protein family, CDS1 is known to catalyze the conversion of phosphatidic acid (PA) to CDP-diacylglycerol (CDP-DAG), an essential intermediate in the synthesis of phosphatidylglycerol, cardiolipin and phosphatidylinositol. Synonyms for this target antigen include CDP-DAG synthase 1, CDP-DG synthase 1, CDP-DG synthetase 1, CDP-diacylglycerol synthase (phosphatidate cytidylyltransferase) 1, and phosphatidate cytidylyltransferase 1.
