摘要: 本研究运用生物信息学方法对水牛信号转导子和转录激活子1(signal transduction and activators of transcription 1,STAT1)基因进行电子克隆及其序列分析。以牛STAT1基因序列作为探针电子克隆了水牛STAT1基因完整的编码序列并进行了RT-PCR验证。序列分析结果表明,水牛的STAT1基因序列长3437 bp,包含1个2244 bp的开发阅读框,共编码747个氨基酸。该基因cDNA编码区序列与普通牛、绵羊、人、猪、大鼠、小鼠和山羊同源性比对结果表明,其相似性分别为99%、98%、89%、93%、86%、85%和87%。经聚类分析结果表明,水牛与普通牛的分子进化关系最近。

Abstract: The buffalo STAT1 gene was silico cloned and analyzed by bioinformatics method in this study. Using the Bos taurus STAT1 sequences to get and identify the buffalo STAT1 gene sequences by the silico cloning and RT-PCR technology. The results showed that the buffalo STAT1 gene length size was 3437 bp, contained an open reading frame (ORF) of 2244 bp that encoded 747 amino acids. The CDS of the obtained buffalo STAT1 gene showed that 99%,98%,89%,93%,86%,85% and 87% identity with that of Bos taurus, Ovi saries, Homo sapiens, Sus scrofa, Rattus norvegicus, Mus musculus and Capra hircus. Analysis of the phylogenetic tree showed that the nearest relationship existed between buffalo and Bos taurus.
