Abstract

Two 12 kDa FK506-binding protein (FKBP12) genes were isolated and characterized from Chinese oak silkworm Antheraea pernyi , an important agricultural and edible insect, designated ApFKBP12 A and B, respectively. Both ApFKBP12 A and B contained 108 amino acids with 82% sequence identity. Phylogenetic analysis showed that FKBP12 B sequences of A. pernyi, Bombyx mori , and Danaus plexippus were clearly separated from FKBP12 A sequences of these three species, suggesting that insect FKBP12 A and B may have been evolving independently. RT-PCR analyses revealed that two ApFKBP12 genes were expressed during the four developmental stages and in all tested tissues, and that the mRNA expression level of the ApFKBP12 A gene was significantly higher than that of the ApFKBP12 B gene. After heat shock treatment, expressions of the two FKBP12 genes were up-regulated, but at different time points. The results suggested that each paralogue of the FKBP12 genes may play a distinct functional role in the development of A. pernyi.
