Detour to Death

Protein kills cells by diverting electrons and crafting free radicals

Abstract: Construction signs steer traffic around trouble, but new work reveals a diversion that routes cells into danger. A protein named p66Shc funnels electrons down an unusual path and uses them to make cell-killing compounds instead of energy. The results might help researchers understand why mice without the protein survive unusually well.
