General annotation (Comments)

Function

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 ICAM1 to provide virion attachment to target cell By similarity.

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. Ref.3

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.

Catalytic activity

Nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1).

Selective cleavage of Tyr-|-Gly bond in the picornavirus polyprotein.

Selective cleavage of Gln-|-Gly bond in the poliovirus polyprotein. In other picornavirus reactions Glu may be substituted for Gln, and Ser or Thr for Gly.

NTP + H2O = NDP + phosphate.

Subunit structure

Capsid proteins interact with host ICAM1 By similarity.

Protein VP1: Virion. Host cytoplasm Potential.

Protein 2B: Host cytoplasmic vesicle membrane; Peripheral membrane protein; Cytoplasmic side Potential. Note: Probably localizes to the surface of intracellular membrane vesicles that are induced after virus infection as the site for viral RNA replication. These vesicles are derived from the endoplasmic reticulum By similarity.

RNA-directed RNA polymerase 3D-POL: Host cytoplasmic vesicle membrane; Peripheral membrane protein; Cytoplasmic side Potential. Note: Probably localizes to the surface of intracellular membrane vesicles that are induced after virus infection as the site for viral RNA replication. These vesicles are derived from the endoplasmic reticulum By similarity.

Post-translational modification

Specific enzymatic cleavages in vivo by the viral proteases yield a variety of precursors and mature proteins. Polyprotein processing intermediates such as VP0 which is a VP4-VP2 precursor are produced. During virion maturation, non-infectious particles are rendered infectious following cleavage of VP0. This maturation cleavage is followed by a conformational change of the particle By similarity.

VPg is uridylylated by the polymerase and is covalently linked to the 5'-end of genomic RNA. This uridylylated form acts as a nucleotide-peptide primer for the polymerase By similarity.

Myristoylation of VP4 is required during RNA encapsidation and formation of the mature virus particle By similarity.

Sequence similarities

Belongs to the picornaviruses polyprotein family.

Contains 2 peptidase C3 domains.

Contains 1 RdRp catalytic domain.

Contains 1 SF3 helicase domain.
