PINK1/Parkin-mediated ubiquitin-dependent mitophagy is a key regulator of browning in inguinal white adipose tissue (iWAT). Here, the authors report that PNPLA7, an Endoplasmic Reticulum and mitochondria-associated membrane (MAM) protein, inhibits browning of iWAT by promoting PINK1/Parkin-mediated mitophagy upon cold challenge or adrenergic receptor agonist treatment.
