Abstract:

In order to study the structure and function of PHB gene in Meiren yak,and to explore its expression in different tissues at 7-day-old and adult cattle.This study cloned the coding region of PHB gene from Meiren yak kidney tissue cDNA as a template.The gene sequence was analyzed by bioinformatics and the physical and chemical properties of the protein were predicted.The relative expression levels of PHB gene in 8 tissues of Meiren yak at two ages were detected by Real-time Fluorescence Quantitative (RT-qPCR).The results showed that the CDS region of the PHB gene of Meiren yak was 819 bp in length,encoding 272 amino acids.The results of homology analysis showed that Meiren yak had the highest homology with common cattle (99.1%).The analysis of PHB protein showed that there was one potential N-glycosylation site and two potential O-glycosylation sites in the PHB protein.Its amino acid isoelectric point was 5.55,the instability coefficient (Ⅱ) was 46.07,and the total average hydrophobicity was 0.045,which was predicted to be an unstable hydrophobic protein.Subcellular localization showed that PHB protein was located in the mitochondria (30.4%),and there were 15 potential phosphorylation sites in the protein.The high-level structure of PHB protein was interconnected by α-helix (56.25%),random coil (22.43%),extended chain (16.54%) and β-corner (4.78%).The results of RT-qPCR showed that the PHB gene was expressed in eight tissues of Meiren yak at two developmental stages.The expression of PHB gene in 7 tissues decreased with the growth and development of Meiren yak.The expression of PHB gene in liver,spleen,lung,fat and testis decreased significantly with age (P<0.05).
