The signalling pathway by which ER damage triggers apoptosis remains unclear. Oakes and colleagues identify CT10-regulated kinase (CRK) as a pro-apoptotic protein induced by ER stress. Such stress leads to the accumulation of cleaved CRK fragments at mitochondria, sensitizing them to cytochrome c release in a cell-free system.
