This study reveals that thermogenic stimuli activate mitochondrial proteolysis via LONP1 to sustain the succinate levels required for efficient conversion of white adipocytes to beige adipocytes. Our work highlights mitochondrial proteases (mitoproteases) as a link between environmental stimuli, metabolite levels and cell identity switching.
