NOVEL FOLD REVEALED BY THE STRUCTURE OF A FAS1 DOMAIN PAIR FROM THE INSECT CELL ADHESION MOLECULE FASCICLIN I
Overview
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.
