Cloning,Bioinformatics and Tissue Differential Expression Analysis of PRDM16 Gene in Qinghai Plateau Yak

In this study,the part coding region of PRDM16 gene of the Qinghai plateau yak was cloned and its bioinformatics and differential expression of PRDM16 gene of muscle tissue were analyzed in different sex individual.The PRDM16 gene part of CDS region was cloned from the longissimus dorsi muscle tissue of Qinghai plateau yak,analyzed its characteristics of bioinformatics and detected gene expression levels of different sex individuals in muscle tissue by Real-time PCR.The results showed that the sequence length of the cloned fragment was 323 bp,the homology between Qinghai plateau yak and cattle was 100%.It encoded 99 amino acids,containing domains of MDS1-EVI1 (complex locus protein MDS1) family proteins function,CATH protein function and typical structure of the curly spiral.PRDM16 protein was 20% of the similarity with people methyltransferase protein domain PR protein 1.PRDM16 gene expression of female yak was significantly higher than male yak's in longissimus dorsi muscle tissue (P<0.01).The test results provided not only research foundation for genetic progress but also technical references for yak meat quality analysis.
