== Function ==

[https://www.uniprot.org/uniprot/POLG_HRV14 POLG_HRV14] 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 (By similarity). The capsid interacts with human ICAM1 to provide virion attachment to target cell. This attachment induces virion internalization predominantly through clathrin- and caveolin-independent endocytosis. VP0 precursor is a component of immature procapsids (By similarity). Protein 2A is a cysteine protease that is responsible for the cleavage between the P1 and P2 regions. It cleaves the host translation initiation factor EIF4G1, in order to shut down the capped cellular mRNA transcription (By similarity). Protein 2B affects membrane integrity and cause an increase in membrane permeability (By similarity). Protein 2C associates with and induces structural rearrangements of intracellular membranes. It displays RNA-binding, nucleotide binding and NTPase activities (By similarity). Protein 3A, via its hydrophobic domain, serves as membrane anchor (By similarity). Protein 3C is a cysteine protease that generates mature viral proteins from the precursor polyprotein. In addition to its proteolytic activity, it binds to viral RNA, and thus influences viral genome replication. RNA and substrate bind co-operatively to the protease (By similarity). RNA-directed RNA polymerase 3D-POL replicates genomic and antigenomic RNA by recognizing replications specific signals (By similarity).

== Publication Abstract from PubMed ==

SCH 38057 (1-[6-(2-chloro-4-methoxyphenoxy)-hexyl]imidazole hydrochloride) is a new, water-soluble antiviral compound that has inhibitory activities against a number of picornavirus infections. The structure of the human rhinovirus 14 (HRV14) complex with SCH 38057 was determined at 3.0 A resolution by single-crystal diffraction techniques using synchrotron X-radiation. SCH 38057 was found to bind at the innermost end of the hydrophobic pocket within the capsid protein VP1, a locus of binding of other antipicornaviral agents; however, the complex differs from previously reported complexes in two important aspects. It leaves a considerable volume near the entrance to the binding pocket unoccupied. In addition, the alterations in the conformation of the VP1 polypeptide are similar to, but more extensive than those observed in HRV14 complexes with other antiviral agents. Although only 9 amino acids of VP1 have close contacts with the SCH 38057 molecule (within 3.6 A), at least 36 amino acids from both VP1 and VP3 have significantly altered conformations (C alpha movement &gt; 0.5 A versus native). The structures of complexes of HRV14 with SCH 38057 and WIN 51711 are compared. Aromatic ring interactions between picornavirus capsid residues and antiviral inhibitors are proposed to be among the major determinants for positioning of these compounds.
