摘要
The autophagy-dependent selective degradation of mitochondria (mitophagy) as an important role in removing excessive, damaged and dysfunctional mitochondria to maintain a proper cellular homeostasis. Relative to its significance in cell physiology, very little is known about the molecular machinery and regulatory mechanism of mitophagy in mammalian cells or yeast. We found that two mitogen-activated protein kinases (MAPKs) Slt2 and Hog1, are required for mitophagy in Saccharomyces cerevisiae. Slt2 is involved in both mitophagy and pexophagy (the selective degradation of peroxisomes through autophagy), whereas Hog1 functions specifically in mitophagy.
