Lineage for Species: Cricket paralysis virus [TaxId: 12136]

1. Root: SCOP 1.75

2. Class b: All beta proteins [48724] (174 folds)

3. Fold b.121: Nucleoplasmin-like/VP (viral coat and capsid proteins) [88632] (7 superfamilies) sandwich; 8 strands in 2 sheets; jelly-roll; some members can have additional 1-2 strands characteristic interaction between the domains of this fold allows the formation of five-fold and pseudo six-fold assemblies

4. Superfamily b.121.4: Positive stranded ssRNA viruses [88633] (9 families)

5. Family b.121.4.1: Picornaviridae-like VP (VP1, VP2, VP3 and VP4) [88634] (9 proteins) the order of the chains N-VP0-VP3-VP1-C is as in the polyprotein; VP0 is cleaved later upon capsid assembly to VP4 and VP2 there is a different order in the shuffled genome of insect picorna-like proteins (Cricket paralysis virus)

6. Protein Insect picorna-like virus coat proteins [49654] (1 species) different genetic order of VP segments due to extensive genome shuffling

7. Species Cricket paralysis virus [TaxId:12136] [49655] (1 PDB entry)
