CD155, transmembrane glycoprotein, is a member of the immunoglobulin superfamily also known as the human receptor for poliovirus (PVR). CD155 localizes in cell-matrix adhesions and cell-cell junctions. PV receptor CD155 complex with PV (PV1, PV2, and PV3). Both glycosylated and fully deglycosylated CD155 exhibited similar binding sites and orientations in the viral canyon for all three PV serotypes, showing that all three serotypes use a common mechanism for cell entry. It is reported that CD155 and CD112 (nectin-2/PRR-2) are ligands of CD226 (DNAM-1).Synonyms: Necl-5, Necl5, Nectin-like protein 5, PVS, Poliovirus receptor
