Figure 8. The sequence alignment portion of A: Laminin epidermal growth factor (EGF)-like domain and B: Fibronectin type 3 domain, in the long usherin isoform from different species. Both Cys934 (C934) and Trp2744 (W2744) are conserved during evolution. The arrows indicate the mutated residues in Usher syndrome type IIA (USH2A).
