RAF kinases and mitochondria.
Over the past decade, several investigators reported that a fraction of the RAF kinases are recruited to the mitochondria. Although we are still far from a global understanding of the molecular consequences of RAF translocation on mitochondrial physiology and metabolism, the recent description of some molecular interactions that are established by C-RAF in this organelle, principally with the proteins Bcl-2 and Bag-1, provides some clues. Here, we discuss the possible contribution of RAF targeting to mitochondria to their modulation of apoptosis signaling, as well as to this organelle's physiology. In addition, we discuss the possible modulation of the mitochondrial metabolism by RAF oncogenes in the context of cancer.
