Prohibitin 2 Is an Inner Mitochondrial Membrane Mitophagy Receptor
The removal of unwanted or damaged mitochondria by autophagy, a process called mitophagy, is essential for key events in development, cellular homeostasis, tumor suppression, and prevention of neurodegeneration and aging. However, the precise mechanisms of mitophagy remain uncertain. Here, we identify the inner mitochondrial membrane protein, prohibitin 2 (PHB2), as a crucial mitophagy receptor...
متن کاملMitophagy: Permitted by Prohibitin
Autophagic responses specific for damaged or superfluous mitochondria are crucial for the maintenance of cellular and organismal homeostasis. Recent data demonstrate that components of the inner mitochondrial membrane that are unmasked upon outer membrane permeabilization facilitate the autophagic destruction of the organelle.
متن کاملUth1 is a mitochondrial inner membrane protein dispensable for post-log-phase and rapamycin-induced mitophagy.
Mitochondria are turned over by an autophagic process termed mitophagy. This process is considered to remove damaged, superfluous and aged organelles. However, little is known about how defective organelles are recognized, what types of damage induce turnover, and whether an identical set of factors contributes to degradation under different conditions. Here we systematically compared the mitop...
متن کاملTMEM65 is a mitochondrial inner-membrane protein
It has been reported that the expression of TMEM65 is regulated by steroid receptor RNA activator (SRA). To date, however, the localization and function of TMEM65 remained unknown. We analyzed the intracellular localization of TMEM65. Immunoblot and immunostaining analysis revealed mitochondrial localization of TMEM65. Alkali extraction analysis and digitonin extraction test using isolated mito...
متن کاملChChd3, an Inner Mitochondrial Membrane Protein, Is Essential for Maintaining Crista Integrity and Mitochondrial Function*
The mitochondrial inner membrane (IM) serves as the site for ATP production by hosting the oxidative phosphorylation complex machinery most notably on the crista membranes. Disruption of the crista structure has been implicated in a variety of cardiovascular and neurodegenerative diseases. Here, we characterize ChChd3, a previously identified PKA substrate of unknown function (Schauble, S., Kin...
