摘要: 目的:克隆Wistar大鼠睾丸水通道蛋白(AQP8)cDNA,构建增强型绿色荧光蛋白(EGFP)与大鼠AQP8的融合蛋白真核细胞表达载体。方法:用RT-PCR钓取AQP8 cDNA编码区全长序列,测序鉴定,将AQP8 cDNA亚克隆于pEGFP-C1基因的下游。结果:①AQP8 cDNA测序结果与登录在GenBank上的大鼠AQP8基因序列(GenBank登录号:NM_019158)高度同源,但PCR产物的序列分析结果中发现4个碱基序列与已发表的AQP8序列不同:NM_019158的第135~137位碱基分别是C、A和G,而测序结果缺乏这3个碱基,NM_019158的第311位为A,而测序结果为G;②酶切鉴定在表达载体pEGFP-C1中AQP8 cDNA融合于EGFP基因的下游。结论:pEGFP-C1-AQP8融合蛋白的表达载体构建成功。

Abstract: Objective To clone aquaporin 8 (AQP8) cDNA of testis in Wistar rats and construct the eucaryotic expression vector of enhance green fluorescent protein (EGFP) and AQP8 fusion protein.Methods The full sequence of AQP8 was fished by RT-PCR and sequenced, then it was recombined in the downstream of the pEGFP-C1 gene. Results The sequence of AQP8 cDNA of Wistar rat was homology with NM_019158(access number logged in GenBank),but there were 4 different bases:P135-137 of NM_019158 partly were C,A and G,but the sequencing result was absence;P311 of NM_019158 was A,but the sequencing result was G. The recombinant pEGFP-C1-AQP8 was identified by enzyme digestion. Conclusion The recombinant pEGFP-C1-AQP8 is constructed successfully.
