Function

[POLS_CRPVC] Structural polyprotein: precursor of all the viral capsid proteins. Capsid protein 1, together with capsid proteins 2 and 3, form an icosahedral capsid protecting the viral RNA genome. The icosahedral capsid has a pseudo-T=3 symmetry with a diameter of approximately 300 Angstroms, and is composed of 60 copies of each CP1, CP2, and CP3. CP1 is situated at the 12 fivefold axes, whereas CP2 and CP3 are located at the quasi-sixfold axes. All these proteins contain a beta-sheet structure called beta-barrel jelly roll. Capsid protein 4 is a tstructural component of the icosahedral capsid protecting the genomic RNA. It may play an important role in capsid assembly. Capsid protein 2, together with capsid proteins 1 and 3, form an icosahedral capsid protecting the viral RNA genome. The icosahedral capsid has a pseudo-T=3 symmetry with a diameter of approximately 300 Angstroms, and is composed of 60 copies of each CP1, CP2, and CP3. CP1 is situated at the 12 fivefold axes, whereas CP2 and CP3 are located at the quasi-sixfold axes. All these proteins contain a beta-sheet structure called beta-barrel jelly roll. Capsid protein 3, together with capsid proteins 1 and 2, form an icosahedral capsid protecting the viral RNA genome. The icosahedral capsid has a pseudo-T=3 symmetry with a diameter of approximately 300 Angstroms, and is composed of 60 copies of each CP1, CP2, and CP3. CP1 is situated at the 12 fivefold axes, whereas CP2 and CP3 are located at the quasi-sixfold axes. All these proteins contain a beta-sheet structure called beta-barrel jelly roll.

Publication Abstract from PubMed

Numerous small, RNA-containing insect viruses are currently classified as picornaviruses, or as 'picorna-like', since they superficially resemble the true picornaviruses. Considerable evidence now suggests that several of these viruses are members of a distinct family. We have determined the gene sequence of the capsid proteins and the 2.4 A resolution crystal structure of the cricket paralysis virus. While the genome sequence indicates that the insect picorna-like viruses represent a distinct lineage compared to true picornaviruses, the capsid structure demonstrates that the two groups are related. These viral genomes are, thus, best viewed as composed of exchangeable modules that have recombined.
