Heat shock induces the association of importin-α1, α4 and α5 with SGs.
Following a 1.5-hour heat shock, the distribution of importin-α proteins and SG marker HuR (A) or G3BP1 (B) was determined. DAPI was used to stain DNA; size bar is 20 µm. The area demarcated by the white square shows a 500× magnified view of SGs.
