Fig. 6. Heat shock affects mobility of GFP-Hsp70 in the nucleus and GFP-Hsp70(K71E) in the nucleus and cytoplasm. HeLa cells were heat shocked and the fluorescence recovery after photobleaching was measured. (A) fluorescence recovery of GFP vector in the nucleus(
), GFP-Hsp70 in the cytoplasm (
), GFP-Hsp70 in the nucleoplasm (
) and GFP-Hsp70 in the nucleolus (solid circles). (B) fluorescence recovery of GFP-Hsp70(K71E) in the cytoplasm (
) and nucleoplasm (
).
