Protein synthesis required to anchor a mutant p53 protein which is temperature-sensitive for nuclear transport.

Abstract excerpt

The p53 protein is rendered temperature-sensitive by a point mutation. Rat cells transformed by this mutant p53 and an activated ras oncogene grow well at 37 degrees C but cease DNA synthesis and cell division when shifted to 32 degrees C. Immunostaining demonstrates that the mutant p53 protein is in the nucleus of the arrested cells at 32 degrees C but in the cytoplasm of the growing cells at 37 degrees C. This...
