THREE-DIMENSIONAL SOLUTION STRUCTURE OF THE EXTRACELLULAR REGION OF THE COMPLEMENT REGULATORY PROTEIN, CD59, A NEW CELL SURFACE PROTEIN DOMAIN RELATED TO NEUROTOXINS
Overview
The cell surface antigen CD59 is an inhibitor of complement-mediated lysis and a member of the Ly6 superfamily (Ly6SF) of cysteine-rich cell-surface molecules whose sequences are related to those of snake venom neurotoxins. The three-dimensional solution structure of a recombinant form of the extracellular region of the molecule (residues 1-70 of the mature protein; sCD59) has been solved by 2D NMR methods. sCD59 is a relatively flat, disk-shaped molecule consisting of a two-standed beta-sheet finger loosely packed against a protein core formed by a three-stranded beta-sheet and a short helix. Structure calculations allowed an unambiguous assignment of the disulfide-bonded cysteine pairs as 3-26, 6-13, 19-39, 45-63, and 64-69. The topology of sCD59 is similar to that of the snake venom neurotoxins and consistent with an evolutionary relationship existing between the Ly6SF and the neurotoxins.
