目的:克隆与分析小鼠不同剪切的Lims基因。方法:应用巢式RT-PCR,以小鼠cDNA 为模板,扩增Lims基因不同剪切子,构入PinPointTM Xa-1T 质粒,测序鉴定。结果:测序表明克隆了新的Lims基因变异剪切体Lims E,该变异剪切体编码区为1 164 bp, 编码387个氨基酸。结论: 比较基因组学分析显示,成功地克隆了一新的小鼠Lims基因剪切子Lims E,为进一步研究Lims基因在细胞发育中的功能打下了基础。
Objective:To clone and analyze the different splicing variant of Lims gene in mouse. Methods:Splicing variants of Lims gene were amplified by RT-PCR from mouse cDNA and inserted into PinPointTM Xa-1T vector, two position clones selected by PCR were sequenced. Results:Lism E, a novel splicing variant with a 1164 bp open reading frame(ORF), encoding a 387-amino acid(AA) protein was cloned. Conclusion:Comparative genome analysis displayed Lims E, a novel variant of Lims gene was confirmed in mouse and established the foundation for further to studying the function of Lims E in cell development.
