Implication

Experimental cell study reveals that Mitofilin and CHCHD6 bind Sam50 to sustain cristae architecture, indicating MICOS integrity is vital for mitochondrial energy production.

Key Points

To investigate the direct physical interactions between the MICOS components Mitofilin and CHCHD6 with Sam50 and evaluate their individual roles in cristae ultrastructure and mitochondrial function.
Conducted immunoprecipitation assays with Mitofilin and CHCHD6 antibodies to identify associated protein complexes.
Generated Mitofilin-knockdown and CHCHD6-knockout cell lines using transcription activator-like effector nucleases (TALENs).
Evaluated cristae architecture via transmission electron microscopy (TEM) and measured mitochondrial membrane potential, ATP levels, and binding partner stability via immunoblotting.
Mitofilin and CHCHD6 physically and directly interacted with Sam50 within a complex that also incorporated CHCHD3.
Depletion of Mitofilin disrupted cristae-controlling binding partners, generated vesicle-like cristae morphology, and significantly decreased mitochondrial membrane potential and intracellular ATP content.
Knockout of CHCHD6 reduced cristae density without affecting Mitofilin binding partners or significantly impairing mitochondrial membrane potential and ATP content.
