Mitochondrial fusion and fission accompany adaptive responses to stress and altered metabolic demands. Inner membrane fusion and cristae morphogenesis depends on Optic Atrophy 1 (Opa1), which is expressed in different isoforms and is cleaved from a membrane-bound, long to a soluble, short form. Here...

Replication and expression of the mitochondrial genome depend on the sufficient supply ofnucleotide building blocks to mitochondria. Dysregulated nucleotide metabolism is detrimental tomitochondrial genomes and can destabilise mitochondrial DNA and trigger inflammation. Here, wereport that a mitocho...

Single nucleotide polymorphisms in the FTO gene encoding a m6A demthylase are associated with obesity and cancer development. However, the functional role of FTO in the developemnt of progression of hepatocellular carcinoma (HCC) as a proteotypic obesity-associated cancer remains unclear. Here, we h...

Mitochondrial proteases regulate the dynamic properties of the organelle morphology and ensure functional plasticity at the cellular level. The metalloprotease OMA1 mediates constitutive and stress-inducible processing of its substrates in mitochondria, but the number of functionally characterized s...

Mitochondria adapt to different energetic demands reshaping their proteome. Mitochondrial proteases are emerging as key regulators of these adaptive processes. Here, we use a multi-proteomic approach to demonstrate regulation of the m-AAA protease AFG3L2 by the mitochondrial proton gradient, couplin...
