Inhibits p53 binding to mitochondria by reducing its affinity for antiapoptotic proteins Bcl-2 and Bcl-XL. Displays no effect on the transactivational or cell cycle checkpoint control function of p53. Reduces cell death induced by γ-radiation in vitro and protects mice from doses of radiation that cause lethal haematopoietic syndrome.
