Cytoplasmic functions of the tumour suppressor p53
The principal tumour-suppressor protein, p53, accumulates in cells in response to DNA
damage, oncogene activation and other stresses. It acts as a nuclear transcription factor that
transactivates genes involved in apoptosis, cell cycle regulation and numerous other
processes. An emerging area of research unravels additional activities of p53 in the
cytoplasm, where it triggers apoptosis and inhibits autophagy. These previously unknown
functions contribute to the mission of p53 as a tumour suppressor.
