| Abstract: | 【Objective】The purpose of this program was to clone and identify novel genes from an adult Moniezia expansa(M.expansa) cDNA library,and provide a foundation for further research.【Method】A cDNA library was constructed from M.expansa adult stage.Clones were selected randomly from the cDNA library and were sequenced by using the method of expression sequence tags(ESTs).Novel genes were acquired by primer-walking.The cDNA sequence encoding M.expansa PICK1 protein was analyzed,including searching the ORF,translating the nucleotide to protein sequence,similarity searches and secondary structure predication with bioinformatics analysis.【Result】PICK1 genes,1 527 bp and coding for 447 amino acids,was cloned and sequenced,then the sequence was submitted to GenBank and got an accession number,GH291479.The theoretical pI was 5.22 and molecular weight was 50.173 3 ku.【Conclusion】The full-length cDNA encoding M.expansa PICK1 was obtained,which laid the foundation for further functional study of this gene. |
