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.
