猪CKM基因启动子的克隆及分析
首发时间:2011-02-22
摘要:目的:克隆CKM基因的启动子,并分析其顺式作用元件和转录因子结合位点。方法:应用特异引物CKMF/CKMR从猪基因组DNA中扩增CKM基因的5'侧翼片段,通过T/A克隆法对CKM基因的启动子进行克隆,并对PCR鉴定为阳性的克隆子进行测序。利用NNPP、MotifFinder、TFSEARCH、SignalScan、CPGPLOT等生物信息学工具分析其顺式作用元件和转录因子结合位点。结果:克隆得到CKM 5'侧翼1444bp DNA序列,分析表明其包括启动子区,且存在2处CpG岛,具备多种启动子特征元件和转录因子结合位点。结论:成功克隆了CKM基因的启动子。

Cloning and analysis of porcine CKM promoter
Abstract:AIMS: To clone and analyze the promoter region of a porcine gene, CKM. METHODS: The 5' flanking region of CKM gene was amplified from porcine genomic DNA using PCR with specific primers CKMF/CKMR. The promoter of porcine CKM gene was cloned by T/A clone method. The positive clones identified by PCR were then sequenced. The cis-acting elements and transcript factor binding sites were analyzed by bioinformatic tools, such as NNPP, MotifFinder, TFSEARCH, SignalScan, CPGPLOT. RESULTS: 1444bp 5' flanking sequences of porcine CKM gene were cloned. It includes promoter regions, 2 CpG island, some promoter elements and transcript factor binding sites. CONCLUSION: The promoter of porcine CKM gene was successfully cloned.
Keywords: animal genetics breeding and reproduction pig CKM promoter
