Description
BACKGROUND Numerous pro-apoptotic signal transducing molecules act on mitochondria and provoke the permeabilization of the outer mitochondrial membrane, thereby triggering the release of potentially toxic mitochondrial proteins. One of these proteins, apoptosis-inducing factor (AIF), is a phylogenetically old flavoprotein which, in healthy cells, is confined to the mitochondrial intermembrane space. Upon lethal signaling, AIF translocates, via the cytosol, to the nucleus where it binds to DNA and provokes caspase-independent Chromatin condensation. It also acts as an NADH oxidase.1 The apoptogenic and oxidoreductase functions of AIF can be dissociated. Thus, mutations that abolish the AIF-DNA interaction suppress AIF-induced chromatin condensation, yet have no effect on the NADH oxidase activity. Recent studies suggest AIF to be a major factor determining caspase-independent neuronal death, emphasizing the central role of mitochondria in the control of physiological and pathological cell demise. In addition, this gene product induces mitochondria to release the apoptogenic proteins cytochrome c and caspase-9.2 Several AIF isforms have been identified from alternative transcripts.3 The mammalian AIF precursor contains an N-terminal mitochondrial localization sequence (MLS, residues 1-100) and a large C-terminal part (121-610) that shares similarity with bacterial oxidoreductases. The mature form of AIF (57 kDa) is generated by cleaving of the MLS, after import into the mitochondrial intermembrane space.
