Scythe (BAT3; HLA-(B) under bar (a) under bar ssociated (t) under bar ranscript (3) under bar, Bag 6) is a protein that has been implicated in apoptosis because it can modulate the Drosophila melanogaster apoptotic regulator, Reaper. Mice lacking Scythe show pronounced defects in organogenesis and in the regulation of apoptosis and proliferation during mammalian development. However, the biochemical pathways important for Scythe function are unknown. We report here multiple levels of interaction between Scythe and the apoptogenic mitochondrial intermembrane protein AIF ((a) under bar poptosis-(i) under bar nducing (f) under bar actor). Scythe physically interacts with AIF and regulates its stability. AIF stability is markedly reduced in Scythe(-/-) cells, which are more resistant to endoplasmic reticulum stress induced by thapsigargin. Reintroduction of Scythe or overexpression of AIF in Scythe(-/-) cells restores their sensitivity to apoptosis. Together, these data implicate Scythe as a regulator of AIF.
