Abstract excerpt
C4b-binding protein (C4BP) is a multimeric serum protein that is a potent regulator of the classical and lectin complement pathways. The binding site for C4b has been localized to complement control protein (CCP) domains 1-3 of the C4BP alpha-chain and, in particular, to a cluster of positively charged amino acids predicted to be at the interface between CCP 1 and CCP 2. To determine the regions of C4b...
