摘要: 本研究以海南黑山羊睾丸组织为材料,利用RT-PCR和RACE技术获得海南黑山羊小分子热休克蛋白9(small heat shock protein 9,Hspb9)基因完整的CDS序列,并对其进行生物信息学分析。结果表明,克隆得到山羊Hspb9 cDNA 长549 bp,CDS区471 bp,共编码157个氨基酸,提交至GenBank数据库中,登录号为:JX088726。生物信息学分析结果表明,Hspb9编码的蛋白无跨膜区和信号肽,存在多个磷酸化位点;预测Hspb9蛋白二级结构α-螺旋占15.28%,β-折叠占30.57%,无规则卷曲占54.15%;存在1个UBQ结构域;Clustel W方法比对山羊Hspb9与绵羊、牛的同源性最高。

Abstract: RACE and RT-PCR were used to clone the full length of small heat shock protein 9 coding sequence from Hainan Black goat testis and the bioinformatics analysis was performed. The results showed that the full length of Hspb9 cDNA was 549 bp, including 471 bp in CDS which encoded a protein of 157 amino acids. The sequence was submitted to GenBank,Accession No. was JX088726. It had no trans-membrane region and signal peptide of the Hspb9 protein. There were several phosphpryiation sites in the sequence. The protein contained 15.28% of α-helix,30.57% of β-sheet, and 54.15% of coil. An ubiquitin domain (UBQ) was also predicted. The Clustel W alignment results showed that goat Hspb9 had a close relationship with sheep and cattle.
