Mechanisms of mitophagy [PDF]

open access: yesNature Reviews Molecular Cell Biology, 2010
Autophagy not only recycles intracellular components to compensate for nutrient deprivation but also selectively eliminates organelles to regulate their number and maintain quality control. Mitophagy, the specific autophagic elimination of mitochondria, has been identified in yeast, mediated by autophagy-related 32 (Atg32), and in mammals during red ...

Mitophagy in plants

Biochimica et Biophysica Acta (BBA) - General Subjects, 2021
Mitochondria play a central role in primary metabolism in plants as well as in heterotrophic eukaryotes. Plants must control the quality and number of mitochondria in response to a changing environment, across cell types and developmental stages. Mitophagy is defined as the degradation of mitochondria by autophagy, an evolutionarily conserved system ...

Mitophagy receptor FUNDC1 regulates mitochondrial dynamics and mitophagy [PDF]

open access: yesAutophagy, 2016
Mitochondrial fragmentation due to imbalanced fission and fusion of mitochondria is a prerequisite for mitophagy, however, the exact "coupling" of mitochondrial dynamics and mitophagy remains unclear. We have previously identified that FUNDC1 recruits MAP1LC3B/LC3B (LC3) through its LC3-interacting region (LIR) motif to initiate mitophagy in mammalian ...

Yeast mitophagy: Unanswered questions

Biochimica et Biophysica Acta (BBA) - General Subjects, 2021
Superfluous and damaged mitochondria need to be efficiently repaired or removed. Mitophagy is a selective type of autophagy that can engulf a portion of mitochondria within a double-membrane structure, called a mitophagosome, and deliver it to the vacuole for degradation. Mitophagy has significant physiological functions from yeast to human, and recent

Regulation by mitophagy

The International Journal of Biochemistry & Cell Biology, 2014
Eukaryotes employ elaborate mitochondrial quality control to maintain the function of the power-generating organelle. Mitochondrial quality control is particularly important for the maintenance of neural and muscular tissues. Mitophagy is specialized version of the autophagy pathway. Mitophagy delivers damaged mitochondria to lysosomes for degradation.

Mitophagy

Essays in Biochemistry, 2013
Mitophagy describes the selective targeting and degradation of mitochondria by the autophagy pathway. In this process, defective mitochondria are first purged from the mitochondrial network then delivered to the lysosome by the autophagy machinery.
