CRYSTAL STRUCTURE OF THE INSECT IMMUNE PROTEIN HEMOLIN: A NEW DOMAIN ARRANGEMENT WITH IMPLICATIONS FOR HOMOPHILIC ADHESION
Overview
Hemolin, an insect immunoglobulin superfamily member, is a, lipopolysaccharide-binding immune protein induced during bacterial, infection. The 3.1 angstrom crystal structure reveals a bound phosphate, and patches of positive charge, which may represent the lipopolysaccharide, binding site, and a new and unexpected arrangement of four, immunoglobulin-like domains forming a horseshoe. Sequence analysis and, analytical ultracentrifugation suggest that the domain arrangement is a, feature of the L1 family of neural cell adhesion molecules related to, hemolin. These results are relevant to interpretation of human L1, mutations in neurological diseases and suggest a domain swapping model for, how L1 family proteins mediate homophilic adhesion.
