广西巴马小型猪SLA-DQB基因的克隆及序列分析
利用RT-PCR的方法从广西巴马小型猪肝脏组织中扩增SLA-DQB基因的编码区序列,旨在为下一步构建SLA-DQB转基因广西巴马小型猪奠定基础.结果表明,克隆的广西巴马小型猪SLA-DQB基因编码区长687 bp,与GenBank参考序列(NM_001113694)相比,共有15个氨基酸发生突变(位点为10、14、19、27、29、38、39、48、58、61、68、72、76、78、183).与普通猪、其他小型猪、奶牛、人类及小鼠的同源性分别为95.8%、95.8%、88.1%、86.2%和80.0%....

| Bibliography: | 44-1267/S HUO Qiu-hong YANG Xiu-rong HUANG Guang-cheng HUANG Hua-ping GU Hao LAN Gan-qiu JIANG He-sheng (College of Animal Science and Technology, Guangxi University, Nanning 530004, China) Reverse transcription (RT) PCR was used to amplify the coding sequence of SLA-DQB in liver from Guangxi Bama mini-pig in order to prepare for SLA-DQB transgenic Guangxi Bama mini-pig. The result showed that the length of SLA-DQB was 687 bp. 15 missense mutations (Site 10, 14, 19, 27, 29, 38, 39, 48, 58, 61, 68, 72, 76, 78, 183) were found and led to the change of amino acid in SLA-DQB in Guangxi Bama mini-pig compared with reference sequence (NM_001113694). Homological analysis showed that there were 95.8%, 95.8%, 88.1%, 86.2%, 80.0% compared with Sus scrofa, miniature swine, Bos taurus, Homo sapiens, and Mus musculus, respectively.
