Genome polyprotein

UniProtKB accession:  Q66578

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Forms an icosahedral capsid of pseudo T=3 symmetry together with capsid proteins VP1 and VP3 (By similarity). The capsid is 300 Angstroms in diameter, composed of 60 copies of each capsid protein and enclosing the viral positive strand RNA genome (By similarity). Capsid proteins interact with host alpha-V/beta-3 integrin heterodimer to provide virion attachment target cell (PubMed:11160695). This attachment induces virion internalization predominantly through clathrin-mediated endocytosis (PubMed:11160695). Binds packaging signals present in the viral RNA (PubMed:28232749).
