Abstract
By applying the concept of ‘surface-simulation’ synthesis to the combining site of the myeloma protein M-603 we were able to mimic synthetically its phosphorylcholine-binding characteristics. The synthetic surface-simulation peptide was found to bind to phosphorylcholine, whereas a control peptide that had the same amino acid composition but a different sequence showed little or no binding activity. The specificity of the binding was further confirmed by inhibition studies in which the surface-simulation peptide, but not the control peptide, inhibited the binding of 125I-labelled surface-simulation peptide to phosphorylcholine. Furthermore, the surface-simulation peptide was found to completely inhibit the binding of the native myeloma protein, M-603, to phosphorylcholine. The control peptide was unable to inhibit this binding. These findings suggest that surface-simulation synthesis can be effectively employed to mimic synthetically antibody combining sites, and may in the future be a valuable tool with which to manipulate the immune response to clinically important antigens.This publication has 13 references indexed in Scilit:
