Negatively regulates leptin receptor (LEPR) cell surface expression, and thus decreases response to leptin. Negatively regulates growth hormone (GH) receptor cell surface expression in liver. May play a role in liver resistance to GH during periods of reduced nutrient availability.
Subcellular locations: Golgi apparatus membrane, Endosome membrane
Expressed at the highest levels in heart and placenta and at a lesser extent in lung, liver, skeletal muscle, kidney and pancreas.
