猪hnRNPK基因启动子的克隆及序列分析

Cloning and Sequence Analysis of the Promoter Region of Porcine hnRNPK Gene

  • 摘要: 首次克隆了猪hnRNPK基因启动子序列,并进一步对该序列进行了分析.结果显示:该基因启动子约1 kb,与已报道的人的相应序列相似度为78.9%,具有相同的"TCTCGCGAGA"核心启动子序列和转录起始位点.利用在线软件分析发现,猪hnRNPK基因启动子不含TATA盒,而含有CAAT盒的GC富集区,存在两处CpG岛,具有SP1、UCE.2、GCF、EARLY SEQ1、TTR_inverted_repeat、NGFI C、EARLY SEQ1等多种转录因子潜在结合位点,并且具有8种基序结构

     

    Abstract: The porcine hnRNPK gene promoter were cloned firstly and analysis by the bioinformatics software. The results showed that the length of porcine hnRNPK promoter is about 1 kb, and had 78.9 percent of the similarity comparing with human hnRNPK promoter, which had the same core promoters’ sequence of “TCTCGCGAGA” and transcriptional start site. The results of bioinformatics analysis showed that no TATA box and two CpG island are found in porcine hnRNPK gene promoter region, and exited many transcription factorsbinding sites such as SP1, UCE.2、GCF, EARLYSEQ1, TTR_inverted_repeat, NGFIC, and 8 motifs.
