Identification of Novel Stress Granule Components That Are Involved in Nuclear Transport

Heat shock targets importin-β1, but not CAS, to SGs.
In heat-shocked HeLa cells, importin-β1, CAS and HuR (A) or G3BP1 (B) were detected by indirect immunofluorescence. DNA was stained with DAPI; size bar is 20 µm. Magnified views (500×) of SG-containing regions are depicted for stressed cells.
