FunctionSPIKE_ADE12 Forms spikes that protrude from each vertex of the icosahedral capsid. Interacts with host receptor CXCAR to provide virion initial attachment to target cell. Fiber proteins are shed during virus entry, when virus is still at the cell surface (By similarity). Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedBinding of virus particles to specific host cell surface receptors is known to be an obligatory step in infection even though the molecular basis for these interactions is not well characterized. The crystal structure of the adenovirus fiber knob domain in complex with domain I of its human cellular receptor, coxsackie and adenovirus receptor (CAR), is presented here. Surface-exposed loops on knob contact one face of CAR, forming a high-affinity complex. Topology mismatches between interacting surfaces create interfacial solvent-filled cavities and channels that may be targets for antiviral drug therapy. The structure identifies key determinants of binding specificity, which may suggest ways to modify the tropism of adenovirus-based gene therapy vectors. Structural analysis of the mechanism of adenovirus binding to its human cellular receptor, CAR.,Bewley MC, Springer K, Zhang YB, Freimuth P, Flanagan JM Science. 1999 Nov 19;286(5444):1579-83.
