DOI: 10.1016/j.str.2021.08.006
Abstract: Electron transfer between respiratory complexes drives transmembrane proton translocation, which powers ATP synthesis and membrane transport. The homodimeric respiratory complex III (CIII2) oxidizes ubiquinol to ubiquinone, transferring electrons to cytochrome c and translocating protons through… read more here.

DOI: 10.1038/s41598-019-47018-6
Abstract: Muscle diseases display mitochondrial dysfunction and oxidative damage. Our previous study in a cardiotoxin model of myodegeneration correlated muscle damage with mitochondrial dysfunction, which in turn entailed altered mitochondrial proteome and oxidative damage of mitochondrial… read more here.

DOI: 10.1073/pnas.2120476119
Abstract: Significance Microproteins are a growing class of versatile small proteins previously overlooked by standard gene annotation methods due to their small size. Here we characterize mitolamban as a cardiac-enriched inner mitochondrial membrane–localized microprotein, which interacts… read more here.
