Role of MINOS in Mitochondrial Membrane Architecture: Cristae Morphology and Outer Membrane Interactions Differentially Depend on Mitofilin Domains

The mitochondrial inner membrane contains a large protein complex crucial for membrane architecture, the mitochondrial inner membrane organizing system (MINOS). MINOS is required for keeping cristae membranes attached to the inner boundary membrane via crista junctions and interacts with protein complexes of the mitochondrial outer membrane. To study if outer membrane interactions and maintenance of cristae morphology are directly coupled, we...
