In this study, a full-length heat shock protein88 complementary DNA (cDNA) of Paecilomyces tenuipes Jocheon-1 was obtained by screening of P. tenuipesJocheon-1 Uni-Zap cDNA library and 5' RACE polymerase chain reaction. The Paecilomyces tenuipes Jocheon-1 heat shock protein88 cDNA contains an open reading frame of 2,139 bp encoding 713 amino acid residues. The deduced amino acid sequence of the P. tenuipes Jocheon-1 HSP88 cDNA showed 77% identity to N. haematococca HSP88 and 45-76% identity to other fungi HSP88. Phylogenetic analysis and BLAST program analysis confirmed that the deduced amino acid sequences of the P. tenuipes Jocheon-1 HSP88 gene belonged to the ascomycetes group within the fungal clade and P. tenuipes Jocheon-1 HSP88 also contains the conserved ATPase domain at the N-terminal. The cDNA encoding P. tenuipes Jocheon-1 HSP88 was expressed as a 88 kDa polypeptide in baculovirus-infected insect Sf9 cells. Under different stress conditions, mRNA expression of P. tenuipes Jocheon-1 HSP88 were quantified by real-time PCR and the result showed that heat shock stress affected the mRNA expression levels of P. tenuipes Jocheon-1 HSP88.
