Crystal structure of anti-human cytomegalovirus antibody 8f9 plus gB peptideCrystal structure of anti-human cytomegalovirus antibody 8f9 plus gB peptide
Structural highlights
FunctionPublication Abstract from PubMedImmunoglobulin genes are generated somatically through specialized mechanisms resulting in a vast repertoire of antigen-binding sites. Despite the stochastic nature of these processes, the V-genes that encode most of the antigen-combining site are under positive evolutionary selection, raising the possibility that V-genes have been selected to encode key structural features of binding sites of protective antibodies against certain pathogens. Human, neutralizing antibodies to human cytomegalovirus that bind the AD-2S1 epitope on its gB envelope protein repeatedly use a pair of well-conserved, germline V-genes IGHV3-30 and IGKV3-11. Here, we present crystallographic, kinetic and thermodynamic analyses of the binding site of such an antibody and that of its primary immunoglobulin ancestor. These show that these germline V-genes encode key side chain contacts with the viral antigen and thereby dictate key structural features of the hypermutated, high-affinity neutralizing antibody. V-genes may thus encode an innate, protective immunological memory that targets vulnerable, invariant sites on multiple pathogens. Germline V-genes sculpt the binding site of a family of antibodies neutralizing human cytomegalovirus.,Thomson CA, Bryson S, McLean GR, Creagh AL, Pai EF, Schrader JW EMBO J. 2008 Oct 8;27(19):2592-602.
