Lower activity of MATα1, which catalyzes the synthesis of the methyl donor S-adenosylmethionine, and mitochondrial dysfunction occur in alcohol-associated liver disease (ALD). Here the authors report that the peptidyl-prolyl cis/trans isomerase PIN1 mediates a selective depletion of MATα1 in the mitochondria, which contributes to mitochondrial dysfunction and fat accumulation, in mouse models of ALD.
