G3BP1 and infection: G3BP1 colocalization with the ZIKV viral RNA (vRNA) was also increased in the P525L FUS relative to the WT FUS SNs (ZIKV, LL WT vs. LL MUT, p < 0.001, 1way ANOVA, Tukey post-test for multiple comparisons; Figures 4C,E), suggesting that, despite ZIKV preventing the formation of SGs, SNs with mutant FUS were more sensitive to, and less able to control, the cellular stress induced by the infection.
