Positive-strand RNA viruses, including picornaviruses, utilize cellular machinery for genome replication. Previously, we reported that each of the 2B, 2BC, 2C, 3A, and 3AB proteins of Aichi virus (AiV), a picornavirus, forms a complex with the Gol...
Phosphatidylinositol 4-kinase IIIβ (PI4KB) is a host factor required for the replication of certain picornavirus genomes. We previously showed that nonstructural proteins 2B, 2BC, 2C, 3A, and 3AB of Aichi virus (AiV), a picornavirus, interact with...

Phosphatidylinositol 4-kinase III beta (PI4KB) is a host factor required for genome RNA replication of enteroviruses, small non-enveloped viruses belonging to the family Picornaviridae. Here, we demonstrated that PI4KB is also essential for genome...

Picornavirus genomes are translated into a single large polyprotein, which is processed by virus-encoded proteases into individual functional proteins. 3C of all picornaviruses is a protease, and the leader (L) and 2A proteins of some picornavirus...

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...
