A second ORF of EV-A71 is efficiently translated in challenged cells. a Schematic diagram of the EV-A71 structure. The EV-A71 genome contains a long ORF flanked by a 5′UTR and 3′UTR. The ORF encodes a 250-kDa polyprotein that is processed into the P1, P2 and P3 regions, which are further cleaved into mature proteins (VP1 to VP4, 2 A to 2 C, and 3 A to 3D). Red box, the second ORF, which begins at the 3’ border of the IRES in the 5’UTR, encodes a 64-76-amino acid polypeptide in diverse sub-genotypes of EV-A71. b Amino acid and nucleic acid sequences of ORF2p from EV-A71 strain AH08/06. c HT-29 cells and isolated primary IECs were infected with EV-A71 or EV-A71ΔORF2p at an MOI of 0.1. Cells were harvested and prepared for immunoblotting at 48 hpi and 72 hpi using antibodies against EV-A71 ORF2p, VP1 and α-tubulin. Source data are provided as a Source Data file
