International consortium maps largest mitochondrial protein atlas

An international consortium has published the largest mitochondrial protein atlas to date, mapping 8,619 proteins across 3,199 families. By comparing data from humans and yeast with five unicellular parasites and a plant, researchers have significantly expanded the known diversity of mitochondrial structures across the evolutionary tree.

The study revealed that approximately 43% of these protein families were not previously documented in Pfam, a major public database. This highlights a significant gap in biological knowledge caused by a historical reliance on a limited number of model organisms.

Of particular medical importance, the atlas identified 33 protein families that are conserved in eukaryotic pathogens but absent in humans. These proteins represent potential “ideal therapeutic targets,” as drugs designed to block them could theoretically attack parasites, such as those responsible for malaria or sleeping sickness, without damaging the host's cells.
