Bioinformatics Analysis on Cell Division Cycle 37 Gene of Taenia solnium and Structural Characteristics of Its Coding Protein

Objective: To analyze and predict the structural characteristics of cell division cycle 37(CDC37)gene of Taenia solnium(Ts) and its encoding protein,and so as to guide the study on its biological function.Methods: Tools provided by bioinformatics webs for analysis on the structure,function and sequences of related gene and protein and bioinformatics software packages were employed to identify TsCDC37 gene from cDNA plasmid library,and bioinformatics analysis on the encoding protein of CDC37 gene was carried out.Results: This gene was 1 203 bp in length and was a full length gene coding 400 amino acids.The coding protein had highest coherence(60%) with CDC37 homolog protein of Schistosoma Japonicum in GeneBank.Relative molecular weight was 46 802.5 ku.The protein was predicted to have 6 B cell epitopes and have no subcellular location sequence.Conclusions: The full length sequence of Ts CDC37 gene is screened from cDNA library of adult Taenia solnium by bioinformatics method.The information about the structure and function of CDC37gene and protein is obtained.
