[[http://www.uniprot.org/uniprot/POLG_HRV2 POLG_HRV2]] Capsid proteins VP1, VP2, VP3 and VP4 form a closed capsid enclosing the viral positive strand RNA genome. VP4 lies on the inner surface of the protein shell formed by VP1, VP2 and VP3. All the three latter proteins contain a beta-sheet structure called beta-barrel jelly roll. Together they form an icosahedral capsid (T=3) composed of 60 copies of each VP1, VP2, and VP3, with a diameter of approximately 300 Angstroms. VP1 is situated at the 12 fivefold axes, whereas VP2 and VP3 are located at the quasi-sixfold axes. The capsid interacts with human VLDLR to provide virion attachment to target cell. This attachment induces virion internalization predominantly through clathrin-mediated endocytosis. VP4 and VP1 subsequently undergo conformational changes leading to the formation of a pore in the endosomal membrane, thereby delivering the viral genome into the cytoplasm.<ref>PMID:11034318</ref> <ref>PMID:12191477</ref> VP0 precursor is a component of immature procapsids (By similarity).<ref>PMID:11034318</ref> <ref>PMID:12191477</ref> Protein 2A is a cysteine protease that is responsible for the cleavage between the P1 and P2 regions.
