UniProtKB description:  Forms an icosahedral capsid of pseudo T=3 symmetry with capsid proteins VP2 and VP3 (PubMed:27511920, PubMed:32152109). The capsid is 300 Angstroms in diameter, composed of 60 copies of each capsid protein and enclosing the viral positive strand RNA genome (PubMed:27511920, PubMed:32152109). Capsid protein VP1 mainly forms the vertices of the capsid (PubMed:27511920, PubMed:32152109). The VP1 C-termini form 60 dominant spike-like protrusions on the surface of the virion (PubMed:27511920). Capsid protein VP1 interacts with host cell receptor CDHR3 to provide virion attachment to target host cells (PubMed:32152109). This attachment induces virion internalization (PubMed:32152109). Tyrosine kinases are probably involved in the entry process (By similarity). After binding to its receptor, the capsid undergoes conformational changes (By similarity). Capsid protein VP1 N-terminus (that contains an amphipathic alpha-helix) and capsid protein VP4 are externalized (By similarity). Together, they shape a pore in the host membrane through which viral genome is translocated to host cell cytoplasm (By similarity).
