Coxsackievirus B3 (CVB3) is one of the major viruses associated with human viral myocarditis, in members of the Picornaviridae order. Cellular localization depends on the activity of nuclear pore complexes, which are composed of nucleoporins (Nups), including Nup62. To better understand interactions between Nup62 and CVB3, we investigated the impact of CVB3 infection on Nup62 levels and the impact of Nup62 production on CVB3 replication in cultured cells. We found that CVB3 infection correlated with decreased Nup62 expression in vitro and that lower levels of Nup62 led to inhibition of CVB3 replication and to decreased activation of AKT and extracellular signal-related kinase. Our study reveals that Nup62 regulates the CVB3 replication during infection.
