CDP-diacylglycerol synthase (CDS) catalyzes the conversion of phosphatidic acid to CDP-diacylglycerol, an important precursor for the synthesis of phosphatidylinositol, phosphatidylglycerol, and cardiolipin. We amplified and sequenced 2,053 bp of the pig CDS1 mRNA. The structure of the pig CDS1 gene was determined, being very similar to that of the human, rat, and mouse genes with respect size and organization of the 13 exons. In addition, we identified three polymorphic positions in exons 10 and 11. One of them, the A/C1006, was genotyped in samples belonging to Iberian, Landrace, Large White, Pietrain, and Meishan pig breeds. Expression of this gene was also analyzed by real-time polymerase chain reaction (PCR) in different tissues showing a high CDS1 expression in testis. Moreover, a 1240-bp fragment of the pig CDS2 mRNA was amplified and sequenced. Finally, the CDS1 and CDS2 genes were physically mapped to porcine chromosomes 8 and 17, respectively, by using the INRA, University of Minnesota porcine Radiation Hybrid panel (IMpRH).
