Characterization of a cDNA and gene encoding a cuticular protein from rigid cuticles of the giant silkmoth, Hyalophora cecropia.
We have isolated a cDNA and gene encoding a protein (HCCP66) found in the rigid cuticles of both larvae and pupae of the silkmoth, Hyalophora cecropia. The cDNA encoded a protein similar to cuticle proteins isolated from several other insects and contained a sequence motif similar to one present in a "family" of cuticular proteins from flexible cuticles. The gene had a structure similar to that of cuticle protein genes isolated from Drosophila melanogaster, albeit with a much larger intron that contained three copies of a transposable element-like sequence similar to short interspersed repeated DNA elements (SINEs). A sequence found 5' to the transcription start site matched the Octamer (Oct) cis-acting element. This sequence was capable of binding protein(s) from whole cell extracts of wing epidermis with high affinity and sequence specificity suggesting a role in transcriptional regulation.
