WitrynaNormally, when mitochondria are healthy, PINK1 is imported into the mitochondrial matrix through the translocase of the outer membrane (TOM) complex. In contrast, when a damaged mitochondrion exhibits a loss of mitochondrial membrane potential, PINK1 accumulates on the OMM [ 133 ], which results in the recruitment of Parkin from the … Witrynaacids, lipids, iron–sulphur clusters and regulate apoptosis. About 99% of mitochondrial proteins are encoded by nuclear genes, so the biogenesis of mitochondria heavily depends on protein import pathways into the organelle. An intricate system of well-studied import machinery facilitates the import of mitochondrial proteins. Witrynacomplexes and lipid-transfer pro-teins in mitochondria now provides the ﬁrst insight into the mechanisms of thesetransport processes, which are of fundamental importance for mitochondrial activities and cell homeostasis.
