FUBP3 and infection: As shown in Fig. 5b, the cytoplasm of overexpressed FUBP3 cells had many positive stains for FUBP3 (Fig. 5b), and after infection with JEV, the intracellular distribution of many FUBP3 (Fig. 5f) was affected by JEV and then co-localized with the viral NS5 protein (Fig. 5g), as shown around the viral replication sites (Fig. 5e).
