title: The secret life of histones.
abstract: Recent evidence reveals an unexpected role for the linker histone H1.2 in DNA damage-induced apoptosis. DNA double strand breaks induce translocation of nuclear H1.2 to the cytoplasm, where it promotes release of cytochrome c from mitochondria by activating the Bcl-2 family protein, Bak.
