鸡GDE4编码基因的克隆与分析

为了揭示鸡甘油磷酸二酯磷酸二酯酶4(GDE4)的结构和功能,采用逆转录PCR的方法克隆了其编码cDNA序列,并对其进行了详尽的生物信息学分析。结果表明,鸡GDE4编码cDNA含有939个核苷酸,编码312个氨基酸;鸡GDE4具有典型甘油磷酸二酯酶蛋白结构域,是一种跨膜蛋白;GDE4是一种进化保守蛋白,在物种间具有较高的一致性;鸡GDE4的三维结构与磷酸丙糖异构酶桶状结构域结构相似,并且其催化位点位于其中。...

glycerophosphodiester phosphodiesterase 4; chicken; encoding sequence; structure
In order to reveal the structure and function of chicken glycerophosphodiester phosphodiesterase 4 (GDE4), the coding cDNA sequence of chicken GDE4 was cloned by reverse transcription PCR and analyzed by bioinformatieal tools in detail. The results showed that coding eDNA of chicken GDE4 contained 939 nucleotides encoding 312 amino acids. Chicken GDE4 was a transmembrane protein with a classical glyeerophosphodiester phosphodiesterase domain, was an evolutionarily conserved protein and had a high similarity anmong sepcies. The 3-D model of chicken GDE4 resembled a triose-phosphate-isomerase (TIM) barrel domain and its catalytic active sites were located in.
