Definition

Cell surface protein used by a virus as an attachment and entry receptor. In some cases, binding to a cellular receptor is not sufficient for infection: an additional cell surface molecule, or coreceptor, is required for entry. Some viruses are able to use different receptors depending on the target cell type. In prokaryotic viruses, cell receptor for virus entry can also be localized on host outer membrane, pilus or flagellum.
