  • PubMed Abstract: 

    Fasciclin I is an insect neural cell adhesion molecule consisting of four FAS1 domains, homologs of which are present in many bacterial, plant, and animal proteins. The crystal structure of FAS1 domains 3 and 4 of Drosophila fasciclin I reveals a novel domain fold, consisting of a seven-stranded beta wedge and a number of alpha helices. The two domains are arranged in a linear fashion and interact through a substantial polar interface. Missense mutations in the FAS1 domains of the human protein betaig-h3 cause corneal dystrophies. Many mutations alter highly conserved core residues, but the two most common mutations, affecting Arg-124 and Arg-555, map to exposed alpha-helical regions, suggesting reduced protein solubility as the disease mechanism.
