...when it should be dying. The pro-death part of the apoptosis
toolbox includes a number of molecules known as BH3-only proteins. To ensure that cells destroy themselves when appropriate, despite contrary signals from anti-death molecules, BH3-only proteins contain a peptide subunit, termed "BH3", that is made o...
