p53 and apoptosis: it's not just in the nucleus anymore

Mol Cell. 2003 Mar;11(3):552-4. doi: 10.1016/s1097-2765(03)00106-0.

Abstract

The tumor suppressor p53 triggers apoptosis in response to a variety of stress stimuli. Its role as a transcription factor modulating gene expression has been clearly implicated in this process. Two recent publications now argue for an additional direct role of p53 at the mitochondria in inducing apoptosis.
