  • Title: Isolation and expression analysis of a homolog of the 14-3-3 epsilon gene in the diamondback moth, Plutella xylostella.

    Abstract:
    A full-length 14-3-3 gene homolog (also referred to as the Px14-3-3 epsilon "ε" or Px14-3-3ε gene) was cloned from cDNA of the diamondback moth, Plutella xylostella. The Px14-3-3 transcript is 789 nucleotides in length, and the predicted polypeptide is 263 amino acids in length, with a calculated molecular mass of 29.6 kDa. The Px14-3-3 gene contains the typical and predicted 14-3-3 domains and motifs. The amino acid sequence of the diamondback moth 14-3-3 gene is very similar to that of other insect epsilons (ε) but not to other insect zetas (ζ). In particular, the protein sequence of the Px14-3-3 gene shows high identity to the Bombyx mori epsilon (96.2%). Western blot analysis using an antibody against Px14-3-3ε verified the expression of 14-3-3ε in the larval, pupal, and adult stages. The Px14-3-3ε expression patterns in all the different tissue types were examined in the fourth instar larvae. Px14-3-3ε was detected in every tissue examined, including the body fat, hemocytes, brain, gut, and cuticle.
