Vaccinia virus complement control protein (VCP) inhibits both pathways of complement activation through binding the third and fourth components. A homolog of mammalian regulators of complement activation, its ability to bind heparin endows VCP with additional activities of significance to viral infectivity. The structure of VCP reveals a highly extended molecule with a putative heparin recognition site at its C-terminal end. A second cluster of positive charges provides a possibly overlapping binding site for both heparin and complement components. Experiments suggested by the structure indicate that VCP can bind heparin and control complement simultaneously. This, the structure of any intact regulator of complement activation, along with attendant functional insights, will stimulate the design of new therapeutic inhibitors of complement.
