Here the authors demonstrate a mechanism by which PNPLA3 and its risk variant I148M contribute to intracellular lipid metabolism. PNPLA3 interacts with ABHD5 to prevent the PNPLA2–ABHD5 interaction, thereby inhibiting lipolysis in brown adipocytes and promoting lipid storage. The PNPLA3 I148M variant enhances this interaction.
