Summary

Proteins synthesized at a low temperature retained their fluorescence despite a shift to a higher temperature, and when a temperature-sensitive nsp1 mutant expressing GFP-nucleoplasmin was cultured at 23 degrees C and then shifted to 35 degrees C, this protein accumulated in novel nuclear-like compartments devoid of DNA.
