The family should probably be split up into sub-families. Capsid proteins of picornaviruses. Picornaviruses are non-enveloped plus-strand ssRNA animal viruses with icosahedral capsids. They include rhinovirus (common cold) and poliovirus. Common structure is an 8-stranded beta sandwich. Variations (one or two extra strands) occur.

It is VP4 of the viral polyprotein which, in poliovirus, is part of the capsid that consists of 60 copies each of four proteins VP1, VP2, VP3, and VP4 arranged on an icosahedral lattice [1]. VP4 is on the inside and differs from the others in being small, myristoylated and having an extended structure. Productive infection involves the externalisation of the VP4, which is cleaved from the rest, along with the N-terminus of VP1. There thus seem to be three stages of the virus, ie a multi-step process for cell entry involving RNA translocation through a membrane channel formed by the externalised N termini of VP1 [2].
