牦牛DJ-1基因克隆、生物信息学及组织表达分析
Cloning,Bioinformatics,and Tissue Expression Analysis of Yak DJ-1 Gene
摘要
Abstract
In order to study the structure and function of DJ-1 gene in yaks,this experiment used Meiren yak adipose tissue cDNA as a template,cloned the coding sequence(CDS)of yak DJ-1 gene using RT-PCR,and per-formed bioinformatics analysis,including domain prediction and protein physicochemical properties prediction of the gene sequence.Then,tissue expression analysis was performed using RT-qPCR.The results showed that the CDS re-gion of the DJ-1 gene in Meiren yak had a total length of 570 bp and encoded 189 amino acids;the prediction of the DJ-1 domain in yaks showed that there was one PfpI domain containing the Pfam in positions 29-168 of the DJ-1 amino acid sequence.By predicting structure and function of the DJ-1 protein,the results showed no transmembrane structure and no signal peptide region;molecular weight was 20.03531 ku,total number of atoms was 2870,theo-retical isoelectric point was 6.84,instability coefficient was 28.37,and expressed as a stable protein;the fat coeffi-cient was 101.11,with a total average hydrophilicity coefficient of-0.004.It was a hydrophilic protein with a total of 11 phosphorylation sites.Meanwhile,the results of subcellular localization prediction indicated that the DJ-1 pro-tein of Meiren yak was mainly distributed in the cytoplasm and mitochondria.The phylogenetic tree showed that Meiren yak had the closest genetic relationship with wild yaks and European cattle,and the farthest genetic relation-ship with Arctic foxes and wide snouted manatees;the RT-qPCR results showed that it was expressed in the heart,liver,spleen,lungs,muscle,fat,and testicular tissues of adult Meiren yaks,with the highest expression level in the heart and muscle tissues,and the lowest expression level in the liver and testicular tissues.关键词
