摘要: 通过对天祝白牦牛高硫角蛋白基因启动子 B2A 克隆得到其序列,将序列提交到NCBI,登录号:KJ910005,并对其进行生物信息学分析,通过亚细胞定位,磷酸化分析,二级、三级结构和保守结构域预测结果比较,MEGA 5.10 软件进行NJ法进化树构建和MegAlign进行蛋白质相似分析来分析 B2A 基因与 KAP1.1 (Keratin associated protein1.1) 基因的差异性。B2A 基因的CDS区全长为471 bp,共编码156个氨基酸,二级结构含有延伸链、β转角和无规卷曲3种。B2A蛋白和KAP1.1蛋白的亚细胞定位,磷酸化分析,保守结构域,二级结构、三级结构和同源性差异较大。但是从功能预测结果显示2个蛋白功能完全一致,并且使用Clustal X进行氨基酸序列比对分析显示B2A蛋白从第33位开始相对于KA1.1蛋白有10个氨基酸的缺失以外,其余序列之间的保守性相当高。因此,可以证明 B2A 基因是 KAP1.1 基因的基因亚型。

关键词: 牦牛, B2A 基因, KAP1.1蛋白, 基因亚型

Abstract: In this study, the high sulfur keratin B2A promoter of Tianzhu White Yak gene was cloned and got sequence, and analyzed the bioinformatics.Comparison of forecasting results by subcellular localization, phosphorylation analysis, secondary structure of proteins, tertiary structure, MEGA 5.10 software by NJ method and phylogenetic tree construction and MegAlign software to analyzed the difference between B2A gene and KAP1.1 gene. B2A gene CDS region was 471 bp, encoding a protein with 156 amino acids, the secondary structures were mainly composed of extended strand, beta turn and random coil.B2A and KAP1.1 protein of subcellular localization, phosphorylation analysis, conserved domains, secondary structure, tertiary structure and homology were different.But from the function prediction results showed that the two protein's function were exactly same, and Clustal X software was used to compare the amino acid sequence.B2A protein compared with KAP1.1 protein has ten amino acids deletion at position 33, the remaining sequence has very high conserved between two proteins.So it was proved that the B2A gene was KAP1.1 gene sub gene.

Key words: Yak, B2A gene, KAP1.1 protien, Sub gene
