Chitin binding domain(IPR002557) is the accession number for the chitin binding domain. Peritrophin-A is a protein found in the peritrophic matrix of insect and animal chitinases and other chitin-binding proteins. There are cases where the rods Similarly, this domain was also discovered in coronaviruses. Located outside the cell, this region is rich in aromatic residues and a hexacysteine motif. It has been demonstrated that only proteins with these domains are able to bind chitin. Collagen binding domain (IPR008456) partially overlap exists between this site and a peptide sequence known to be important for collagen binding. Among the proteins involved in the development of striated fibers is fibrillar collagen, which is represented by the Fibrillar collagen, C-terminal domain (IPR000885). Binding to various substrates is facilitated by these domains. The C-terminus of fibrillar collagen contains one of these domains. The Chinese wheat mosaic virus coat protein was compared to insect-related sequences (aphid, leafhopper, mite, planthopper) downloaded from the Uniprot database using the built-in MEME program. Table shows that the entire coat protein region contains chitin-binding, collagen, fibrillar, and LIM-type domains. This suggests that coat protein's Chitin-binding, Collagen-binding, and Fibrillar domains bind to Chitin, Collagen, and Fibrillar polymers in a protein-protein interaction-like fashion.
