PCBP1 and infection: In EV71-infected cells, EV71 3C protein was expressed and mainly distributed in the cytoplasm at 6 h and 12 h post-infection (Fig. 4Bf and 4Bj), while majority of PCBP1 in the cytoplasm of EV71-infected cells (Fig. 4Bg and 4Bk) and co-localized with EV71 3C protein (Fig. 4Bh and 4Bl).
