Spatial control of mitochondrial ubiquitination by the AMBRA1-RMC1-HUWE1 axis.
Mitochondrial ubiquitination is a central component of mitochondrial quality control. The PINK1 (PTEN induced kinase 1)-PRKN (parkin RBR E3 ubiquitin protein ligase) pathway established how loss of mitochondrial membrane potential can trigger a phospho-ubiquitin feed-forward cascade on the outer mitochondrial membrane...
