摘要:

旨在克隆鸡Heme oxygenase 1HO-1)基因,探明其蛋白结构、功能及组织表达特性。以海兰白鸡(W-36)为材料,利用RT-PCR技术克隆鸡HO-1基因CDS区,利用生物信息学方法预测蛋白结构与功能,应用qRT-PCR检测组织表达特性。结果表明,鸡HO-1基因的CDS891 bp,编码296个氨基酸,其核苷酸和氨基酸序列与其他种属间的差异较大。鸡HO-1为跨膜非分泌蛋白,具有HO家族的结构域,酶分类为EC1.14.99.3,能够结合HEMBLAOXNQ80SUCTRENa+等分子。鸡HO-1基因在组织内广泛表达,在动脉、脑干、大脑、坐骨神经、十二指肠及小肠等组织表达量较高。预测HO-1蛋白具有调控糖类和盐类等相关分子功能作用,其在组织中广泛表达,在循环系统、神经系统和消化系统中具有重要的生物学功能。

Abstract:

The aim of this study was to clone the chicken Heme oxygenase 1 (HO-1) gene,predict its protein structure and function,and reveal its expression characteristics in tissues.In this study,Hailan White fowl (W-36) was used as experimental animal,the CDS region of chicken HO-1 gene was cloned by qRT-PCR,the protein structure and function were predicted by using bioinformatics,RT-PCR was used to analyze the expression characteristics in tissues.These results showed that the CDS of chicken HO-1 gene was 891 bp,encoding 296 amino acids.The conservation of its nucleotide and amino acid sequences were not high compared with other species.The protein of chicken HO-1 was transmembrane and non-secretory,it had a domain of the HO family,it is classified in EC1.14.99.3.It could bind to HEM,BLA,OXN,Q80,SUC,TRE and Na+ molecules,the HO-1 was expressed widely in tissues,and the expression level was higher in the brain,brain stem,artery,sciatic nerve,duodenum and small intestine.HO-1 protein is predicted that it can regulate the sugar and salt function,and is expressed widely in tissues,with important biological function in the circulatory system,nervous system and digestive system.
