The 3' noncoding region (NCR) of the genomic picornaviral RNA is believed to contain major cis-acting signals required for negative-strand RNA synthesis. The 3' NCR of foot-and-mouth disease virus (FMDV) was studied in the context of a full-length infectious clone in which the genetic element was deleted or exchanged for the equivalent region of a distantly related swine picornavirus, swine ves...
An analysis of published nucleotide sequences of the 5'-untranslated region (5'-UTR) of 7 cardioviruses and 3 aphthoviruses has allowed us to derive a consensus secondary structure model that differs from that previously proposed for the 5'-UTR of entero- and rhinoviruses, though all these viruses belong to the same family, Picornaviridae. The theoretical model derived here was experimentally s...
We recently compared the efficiency of six picornaviral internal ribosome entry segments (IRESes) and the hepatitis C virus (HCV) IRES for their ability to drive internal initiation of translationin vitro. Here we present the results of a similar comparison performed in six different cultured cell lines infected with a recombinant vaccinia virus expressing the T7 polymerase and transfected with...
Foot-and-mouth disease virus (FMDV), the causative agent of foot-and-mouth disease, is an Aphthovirus within the Picornaviridae family. During infection with FMDV, several host cell membrane rearrangements occur to form sites of viral replication. FMDV protein 2C is part of the replication complex and thought to have multiple roles during virus replication. To better understand the role of 2C i...
Foot-and-mouth disease virus (FMDV) is the type species of the Aphthovirus genus of the Picornaviridae: Infection by picornaviruses results in a major rearrangement of the host cell membranes to create vesicular structures where virus genome replication takes place. In this report, using fluorescence and electron microscopy, membrane rearrangements in the cytoplasm of FMDV-infected BHK-38 cells...
Equine rhinitis A virus (ERAV) is a member of the genus Aphthovirus, family Picornaviridae, and causes respiratory disease in horses worldwide. To characterize the putative receptor molecule(s) of the ERAV isolate 393/76 (ERAV.393/76) on the surface of Vero and other cells, an assay was developed to measure the binding of purified biotinylated ERAV.393/76 virions to cells by flow cytometry. Usi...
Foot-and-mouth disease virus (FMDV) is an aphthovirus that belongs to the Picornaviridae family and causes one of the most important animal diseases worldwide. The capacity of other picornaviruses to express foreign antigens has been extensively reported, however, little is known about FMDV. To explore the potential of FMDV as a viral vector, an 11-amino-acid (aa) HSV epitope and an 8 aa FLAG e...
Among the few non-structural proteins encoded by the picornaviral genome, the 2A protein is particularly special, irrespective of structure or function. During the evolution of the Picornaviridae family, the 2A protein has been highly non-conserved. We believe that the 2A protein in this family can be classified into at least five distinct types according to previous studies. These five types a...
