cuticular protein 49Ae [Drosophila melanogaster]

Protein Classification

chitin-binding domain-containing protein( domain architecture ID 10448777)

chitin-binding domain-containing protein such as insect cuticle proteins, endocuticle structural proteins, and pro-resilin, which plays a central role in flight by providing low stiffness, high strain and efficient energy storage

Insect cuticle protein; Many insect cuticular proteins include a 35-36 amino acid motif known as the R_R consensus. The extensive conservation of this region led to the suggestion that it functions to bind chitin. Provocatively, it has no sequence similarity to the well-known cysteine-containing chitin-binding domain found in chitinases and some peritrophic membrane proteins. Chitin binding has been shown experimentally for this region. Thus arthropods have two distinct classes of chitin binding proteins, those with the chitin-binding domain found in lectins, chitinases and peritrophic membranes (cysCBD) and those with the cuticular protein chitin-binding domain (non-cysCBD).
