IS FR1 THE ANTIBODY'S ACHILLIES HEEL
Overview
Antibodies are the archetypal molecules of the Ig-fold superfamily. Their, highly conserved beta-sheet architecture has evolved to avoid aggregation, by protecting edge strands. However, the crystal structure of a human V, kappa domain described here, reveals an exposed beta-edge strand which, mediates assembly of a helical pentadecameric oligomer. This edge strand, is highly conserved in V kappa domains but is both shortened and capped by, the use of two sequential trans-proline residues in V lambda domains. We, suggest that the exposure of this beta-edge in V kappa domains may explain, why light-chain deposition disease is mediated predominantly by kappa, antibodies.
