摘要: 试验采用RT-PCR方法,以麦洼牦牛脾脏cDNA为模板扩增牦牛低氧诱导因子-1α(hypoxia inducible factor-1α,HIF-1α)基因,并运用生物信息学软件对其序列进行分析。结果发现,扩增得到的麦洼牦牛HIF-1α基因编码区长为2 472 bp,编码823个氨基酸;蛋白质预测结果显示,该蛋白质分子质量为92.13 ku,等电点5.09,为亲水性蛋白,二级结构以随机卷曲和α-螺旋为主,有69个磷酸化位点和4个N-糖基化位点;系统进化树显示,麦洼牦牛与牦牛、野牦牛、普通牛亲缘关系最近。本试验成功克隆麦洼牦牛HIF-1α基因并对其序列进行了分析,为进一步研究HIF-1α基因的功能提供参考。

Abstract: In this study,hypoxia inducible factor-1α(HIF-1α) gene was cloned from yak spleen by RT-PCR,and it was divided into two sections for amplification.The sequence and protein structure were analyzed using related bioinformatics tools.The length of the coding region was 2 472 bp,which encoded 823 amino acids.Its molecule mass was 92.13 ku,and PI was 5.09.It displayed as a hydrophilic protein,whose secondary structure was mainly composed of random coil and α-helix.It had 69 phosphorylation sites and 4 N-glycosylation sites.Phylogenetic tree displayed that Maiwa yak,Bos grunniens,Bos mutus and Bos taurus gathered into one cluster.Maiwa yak HIF-1α gene was successfully cloned in this study,it provided a viable reference for further study of genetic characteristics of HIF-1α.

Key words: Maiwa yak; hypoxia inducible factor-1α; cloning; protein analysis
