Virol. 76:7694-7704(2002). CC -!- FUNCTION: Capsid proteins VP1, VP2, VP3 and VP4 form a closed CC capsid enclosing the viral positive strand RNA genome. VP4 lies on CC the inner surface of the protein shell formed by VP1, VP2 and VP3. CC All the three latter proteins contain a beta-sheet structure CC called beta-barrel jelly roll. Together they form an icosahedral CC capsid (T=3) composed of 60 copies of each VP1, VP2, and VP3, with CC a diameter of approximately 300 Angstroms. VP1 is situated at the CC 12 fivefold axes, whereas VP2 and VP3 are located at the quasi- CC sixfold axes (By similarity). Capsid proteins interact with host CC CD55 to provide virion attachment to target cell. CC -!- FUNCTION: VP0 precursor is a component of immature procapsids (By CC similarity). CC -!- FUNCTION: Protein 2A is a cysteine protease that is responsible CC for the cleavage between the P1 and P2 regions. It cleaves the CC host translation initiation factor EIF4G1, in order to shut down CC the capped cellular mRNA transcription (By similarity). CC -!- FUNCTION: Protein 2B affects membrane integrity and cause an CC increase in membrane permeability (By similarity). CC -!- FUNCTION: Protein 2C associates with and induces structural CC rearrangements of intracellular membranes. It displays RNA- CC binding, nucleotide binding and NTPase activities (By similarity). CC -!- FUNCTION: Protein 3A, via its hydrophobic domain, serves as CC membrane anchor. It also inhibits endoplasmic reticulum-to-Golgi CC transport (By similarity). CC -!- FUNCTION: Protein 3C is a cysteine protease that generates mature CC viral proteins from the precursor polyprotein. In addition to its CC proteolytic activity, it binds to viral RNA, and thus influences CC viral genome replication. RNA and substrate bind co-operatively to CC the protease (By similarity). CC -!- FUNCTION: RNA-directed RNA polymerase 3D-POL replicates genomic CC and antigenomic RNA by recognizing replications specific signals CC (By similarity). CC -!- CATALYTIC ACTIVITY: Nucleoside triphosphate + RNA(n) = diphosphate CC + RNA(n+1). CC -!- CATALYTIC ACTIVITY: Selective cleavage of Tyr-|-Gly bond in the CC picornavirus polyprotein. CC -!- CATALYTIC ACTIVITY: Selective cleavage of Gln-|-Gly bond in the CC poliovirus polyprotein. In other picornavirus reactions Glu may be CC substituted for Gln, and Ser or Thr for Gly. CC -!- CATALYTIC ACTIVITY: NTP + H(2)O = NDP + phosphate. CC -!- SUBUNIT: Capsid proteins interact with host CD55. CC -!- SUBCELLULAR LOCATION: Protein VP2: Virion. Host cytoplasm CC (Potential). CC -!- SUBCELLULAR LOCATION: Protein VP3: Virion. Host cytoplasm CC (Potential). CC -!- SUBCELLULAR LOCATION: Protein VP1: Virion. Host cytoplasm CC (Potential). CC -!- SUBCELLULAR LOCATION: Protein 2B: Host cytoplasmic vesicle CC membrane; Peripheral membrane protein; Cytoplasmic side CC (Potential). Note=Probably localizes to the surface of CC intracellular membrane vesicles that are induced after virus CC infection as the site for viral RNA replication. These vesicles CC are derived from the endoplasmic reticulum (By similarity). CC -!- SUBCELLULAR LOCATION: Protein 2C: Host cytoplasmic vesicle CC membrane; Peripheral membrane protein; Cytoplasmic side CC (Potential). Note=Probably localizes to the surface of CC intracellular membrane vesicles that are induced after virus CC infection as the site for viral RNA replication. These vesicles CC are derived from the endoplasmic reticulum (By similarity). CC -!- SUBCELLULAR LOCATION: Protein 3A: Host cytoplasmic vesicle CC membrane; Peripheral membrane protein; Cytoplasmic side CC (Potential). Note=Probably localizes to the surface of CC intracellular membrane vesicles that are induced after virus CC infection as the site for viral RNA replication. These vesicles CC are derived from the endoplasmic reticulum (By similarity). CC -!- SUBCELLULAR LOCATION: Protein 3B: Virion (Potential). CC -!- SUBCELLULAR LOCATION: Picornain 3C: Host cytoplasm (Potential). CC -!- SUBCELLULAR LOCATION: RNA-directed RNA polymerase 3D-POL: Host CC cytoplasmic vesicle membrane; Peripheral membrane protein; CC Cytoplasmic side (Potential). Note=Probably localizes to the CC surface of intracellular membrane vesicles that are induced after CC virus infection as the site for viral RNA replication. These CC vesicles are derived from the endoplasmic reticulum (By CC similarity). CC -!- PTM: Specific enzymatic cleavages in vivo by the viral proteases CC yield a variety of precursors and mature proteins. Polyprotein CC processing intermediates such as VP0 which is a VP4-VP2 precursor CC are produced. During virion maturation, non-infectious particles CC are rendered infectious following cleavage of VP0. This maturation CC cleavage is followed by a conformational change of the particle CC (By similarity). CC -!- PTM: VPg is uridylylated by the polymerase and is covalently CC linked to the 5'-end of genomic RNA. This uridylylated form acts CC as a nucleotide-peptide primer for the polymerase (By similarity). CC -!- PTM: Myristoylation of VP4 is required during RNA encapsidation CC and formation of the mature virus particle (By similarity). CC -!- SIMILARITY: Belongs to the picornaviruses polyprotein family. CC -!- SIMILARITY: Contains 2 peptidase C3 domains. CC -!- SIMILARITY: Contains 1 RdRp catalytic domain. CC -!- SIMILARITY: Contains 1 SF3 helicase domain.
