摘要:
克隆猪的akirin2基因,并对该基因在猪的18个组织中的分布进行研究。猪akirin2基因编码区全长为612 bp (GenBank登录号KC140110.1),推测的氨基酸序列包含203个氨基酸,为酸性蛋白。利用BLAST工具对克隆到的猪akirin2基因序列与人、大鼠、小鼠、绵羊和牛的序列进行同源性比较。采用软件对氨基酸序列进行分析,用相关序列的比对结果进行系统进化树分析。组织分布结果显示,猪akirin2基因在脑组织中高表达,在淋巴、睾丸中表达量相对较低,在心脏、十二指肠、直肠、皮肤、胸腺中几乎检测不到该基因的表达。序列分析结果显示,猪akirin2基因与绵羊和牛的同源性最高,均为96%,与人、小鼠、大鼠的同源性分别为95%、91%、89%。氨基酸序列分析发现,存在1个10个肽的核定位信号序列19-PASPKRRRCA-28,推测的氨基酸序列的二级结构中含有2个a-螺旋。在重建的系统进化树上,几个不同物种的akirin2蛋白分成3支,结果表明猪akirin2与人、牛和羊的亲缘关系比其与小鼠和大鼠的近,与鸡的亲缘关系最远。
