Summary:【目的】克隆广西巴马小型猪ANK1基因启动子,确定其活性核心区,为研究ANK1基因启动子与肉质性状的相关性及构建动物疾病模型打下基础。【方法】通过在线软件对ANK1基因启动子的转录因子结合位点进行预测,根据转录因子结合位点设计特异引物扩增不同长度的ANK1基因启动子片段,并利用双荧光素酶试剂盒检测其荧光值,以确定不同ANK1基因启动子片段的活性。【结果】发现ANK1基因启动子存在1个转录起始位点(TSS)、2个Cp G岛和多个转录因子结合位点,并以此作为ANK1基因启动子的分段依据,将其分割为P638、P791、P1113、P1163、P1648、P1694、P1796和P2074等8个不同长度的目的片段。成功克隆获得的8个ANK1基因启动子片段经KpnⅠ和HindⅢ双酶切、T4真核表达载体连接、细胞转染等方法构建8个双荧光素酶重组报告基因,双荧光素酶试剂盒检测结果显示,广西巴马小型猪ANK1基因启动子在P1796片段活性最强,与其他片段存在显著差异(P〈0.05)。【结论】成功克隆获得广西巴马小型猪ANK1基因启动子的8个片段,且利用双荧光素酶试剂盒检测确定其核心启动子区域出现在P1796片段。

Objective]In this study, ANK1 gene promoter of Guangxi Bama miniature pig was cloned, and its core activity areas were detected, so as to lay a foundation for researching correlation between ANK1 gene promoter and meat quality traits, and establishing animal disease model. [Method]Transcription factor binding sites of ANK1 promoter were predicted with online software, ANK1 promoter fragments of different lengths were amplified by specific primers based on tran- scription factor binding sites. To determine the activity of different fragments, fluorescence values of different promoter re- gions were tested using dual luciferase kits. [Result]One transcription starting sites(TSS), two CpG islands and multiple transcription factor binding s
