Cloning and Characterization Analysis of Heat Shock Protein 90 Gene from Harmonia axyridis( Pallas)[J]. Acta Scientiarum Naturalium Universitatis SunYatseni, 2010,49(2):72-78.DOI:
The heat shock protein 90 (HSP 90) gene from Harmonia axyridis (Pallas) was cloned using techniques of homological cloning and anchored PCR. The full length of cDNA sequence is 2 480 bp(Genbank number: FJ501962)
containing a 3′UTR (untranslated region) of 200 bp
a 5′UTR of 126 bp
and an ORF of 2 154 bp which encodes a polypeptide of 717 amino acids with an estimated molecular weight of 82 230 and p I of 4.96. There are no glycosylation sites
putative transmembrane domain and signature peptide. It contains ATPase conservative domain of (HSP90) in Nsite and EEVD signature sequence on Csite. Compared with Tribolium castaneum
they are 90% identities and Phylogenetic analysis shows that these two species are most closely related. Cloning and comparison analysis of HSP 90 genes from Harmonia axyridis (Pallas) could be useful in the studies of antistress mechanism
tolerance improvement breeding and evolution for these animals.
