These results indicate that core protein – besides its function in viral particle formation – might be involved in the regulation of flavivirus genomic RNA cyclization, and thus virus replication. In this study, we examined the effect of WNV core protein chaperoning on viral 5 -3 UTR annealing, using an in vitro model system with separate 5 and 3 RNAs. We found that core protein binding greatly increases the rate of 5 -3 complex formation, and is required for the interaction when full-length 3 UTR RNAs are used (Fig. 2) . ./cache/cord-290801-dv6aak01.txt ./txt/cord-290801-dv6aak01.txt
