PCBP2 and infection: Surprisingly, although infection with ZIKV strain MR766 was also capable of repressing arsenite-induced SG formation to levels similar to those of DENV infection (Fig. 3D; see also Fig. S4B in the supplemental material), small eIF3B positive-foci, which colocalized with the SG markers Hu protein R (HuR), poly(rC)-binding protein 2 (PCBP2) and TIAR, were detected in around 55% of naive Huh7 cells infected with ZIKV (Fig. S4A and E).
