【摘要】 利用RT-PCR结合测序技术,对牛黄体中促黄体素受体(Luteinizing hormone receptor,LHR)在转录后通过选择性剪接而形成的剪接异构体进行鉴定,并比较不同剪接异构体编码蛋白质氨基酸序列的差异,利用Real-Time PCR对黄体中的LHR剪接异构体进行定量分析,为研究LHR剪接异构体在黄体中的功能奠定基础。结果表明,牛黄体中LHR通过选择性剪接产生了包括全长mRNA在内的6种剪接异构体,其中第11外显子5’端的266个碱基的缺失会使mRNA因发生移码突变而使翻译提前终止。实时定量PCR结果显示,发生外显子缺失的mRNA的表达量总量是全长mRNA表达量的1.94倍。
【Abstract】 In this paper,RT-PCR and sequencing technique was employed to identify the splice variants of Luteinzing hormone receptor(LHR) in bovine corpus luteum.The difference of deduced protein sequence of the variants was compared.And the expression level of these splice variants was quantified by Real-Time PCR.The results indicated that six isoforms of LHR were identified, and variants lacking the first 266 of exon 11 generated a frame shift,and produced a premature codon,.The result of Real-Time PCR showed that total expression of B,C,D,E and F was 1.94 fold compared with A..
