摘 要：
为筛选JAK2基因启动子区SNP及研究其对启动子功能元件的影响,选择品种差异较大的贵州荷斯坦奶牛和务川黑牛构建不同DNA池,直接测序筛选SNP位点。结果表明,JAK2基因5'调控区及第1外显子存在2个SNPs位点,分别为G+5A、G+104A。生物信息学软件预测得到JAK2基因核心启动子区,SNP位点导致9个转录因子结合位点消失,而产生1个新的转录因子结合位点。G+5A对转录因子结合位点、RNA二级结构和CpG岛均有显著影响。

摘 要：
In order to screen the polymorphisms of JAK2 promoter in cattle and analyze the effect of SNPs on function elements of promoter.Two cattle breeds(Wuchuan black cattle and Guizhou Holstein cow)with significant difference in breeds property were selected to construct DNA pools,SNP sites were screened by direct sequencing subsequently.Results showed that 2 single nucleotide polymorphisms(SNPs)were found in the 5' flanking region and part of exon 1 which included G+5A and G+104A.Furthermore,bioinformatics tools were used to predict the core region of the promoter.It demonstrated that 1 new transcription factors binding sites emerged while 9 previous transcription factors binding sites disappeared based on the SNPs found in this study,and it also showed that SNP of G+5A could change the secondary structure of RNA,transcription factors binding sites and range of CpG island dramatically by using various softwares.
