We determined nucleotide sequences and inferred amino acid sequences of viral protein (VP) 4, VP6, VP7, and nonstructural protein 4 genes of a porcine rotavirus strain (SKA-1) from Japan. The strain was closely related to a novel group of human ro...
Aichi virus (AiV), which is associated with acute gastroenteritis in humans, is a member of the genus Kobuvirus of the family Picornaviridae. Picornavirus genome replication occurs in replication complexes that include viral nonstructural proteins...
The Aichi virus 2A protein is not a protease, unlike many other picornavirus 2A proteins, and it is related to a cellular protein, H-rev107. Here, we examined the replication properties of two 2A mutants in Vero cells and a cell-free translation/r...
Secondary structural elements at the 5′ end of picornavirus genomic RNA function as cis-acting replication elements and are known to interact specifically with viral P3 proteins in several picornaviruses. In poliovirus, ribonucleoprotein complex f...
Recombinant rotavirus (RV) with eDNA-derived chimeric VP4 was generated using recently developed reverse genetics for RV. The rescued virus, KU//rVP4(SA11)-II(DS-1), contains SA11 (simian RV strain, G3P[2])-based VP4, in which a cross-reactive neu...

Rotavirus is the leading pathogen for acute gastroenteritis in mammals and birds. Although the reverse genetics system has been utilized in many viruses, the system using a helper virus was developed for rotavirus in 2006. As a step for antigenic ...
Aichi virus is a member of the Family Picornaviridae. This virus was first isolated in 1989 from a stool specimen from a patient with oyster-associated gastroenteritis in Aichi, Japan. We analyzed the function of the 5' terminal region of the...
