March 2022 – Our paper on the respiratory chain complexes from Tetrahymena is out now in Science!!
Structures of Tetrahymena’s respiratory chain reveal the diversity of eukaryotic core metabolism
The lab celebrates!
January 2022 – Our review paper on the accessory subunits of mammalian mitochondrial complex I is out now in Frontiers in Molecular Biosciences!
In this review, we explore the roles of each the accessory subunits by integrating recent high-resolution structures with knockout, assembly, and clinical studies and develop a framework of experimentally testable hypotheses for the function of the accessory subunits.
