HUMAN CD55 DOMAINS 3 & 4
Overview
Decay-accelerating factor (CD55), a regulator of the alternative and, classical pathways of complement activation, is expressed on all, serum-exposed cells. It is used by pathogens, including many enteroviruses, and uropathogenic Escherichia coli, as a receptor prior to infection. We, describe the x-ray structure of a pathogen-binding fragment of human CD55, at 1.7 A resolution containing two of the three domains required for, regulation of human complement. We have used mutagenesis to map biological, functions onto the molecule; decay-accelerating activity maps to a single, face of the molecule, whereas bacterial and viral pathogens recognize a, variety of different sites on CD55.
