CDIPT (CDP-diacylglycerol-inositol 3-phos-phatidyltransferase, EC 2.7.8.11), an integral membrane protein, was found on the cytoplasmic side of the endoplasmic reticulum and the Golgi apparatus.It performed the last step in the de novo biosynthesis of PtdIns.In recent years, PtdIns has been considered as an essential role in energy metabolism, fatty acid metabolic pathway and intracellular signal transduction in eukaryotic cells.In this studay, Real-Time PCR analysis showed that the expression of CDIPT gene was remarkably different in diverse tissues.We also detected the polymorphism of bovine CDIPT gene and analyzed its association with body measurement and meat quality traits of Qinchuan cattle.Blood samples were taken from a total of 638 Qinchuan cattle aged from 18-24 months.DNA sequencing and PCR-RFLP were used to find out CDIPT gene single nucleotide polymorphism (SNP).Three SNPs g.244T>C (NCBI: rs42069760), g.1496G>A and g.1514G>A were found in this study.g.244T>C located at 5untranslated region (5UTR) of exon 1 and showed three genotypes: TT, TC and CC.g.1496G>A and g.1514G>A detected the first time were located in intron 3 and showed the same genotypes: GG, GA and AA.Analysis results showed that the polymorphism of these 3 SNPs was significantly associated with body measurement traits (BMTs) and meat quality traits (MQTs).Based on the results of this study, it is inferred that CDIPT gene may have potential effects on BMTs and MQTs and could be used for marker-assisted selection.
