| - | ==Overview==
| + | |
| - | Vaccinia virus complement control protein (VCP), a homolog of the, regulators of the complement activation family of proteins, inhibits, complement activation through mechanisms similar to human fluid-phase, complement regulators factor H and C4b-binding protein. VCP has a, heparin-binding activity that assists vaccinia in host interactions., Interaction with cell-surface polyanions like heparin is centrally, important in the functioning of fluid-phase complement regulators and is, the basis of host-target discrimination by the alternative pathway. We, report the structure of VCP in complex with a heparin decasaccharide, which reveals changes in VCP that might be pertinent to complement, regulation. Properties that VCP shares with fluid-phase complement, regulators suggest that such conformational changes may be of relevance in, the functioning of other complement regulators. Additionally, comparison, of VCP-heparin interactions with potentially similar interactions in, factor H might enable understanding of the structural basis of familial, hemolytic uremic syndrome, attributed to mutational disruption of heparin, and C3b binding by factor H.
