Low-density lipoprotein receptor-related protein 2 (LRP2)

In the gut, mediates the tubular uptake and clearance of leptin (By similarity). Also mediates transport of leptin across the blood-brain barrier through endocytosis in the choroid plexus epithelium (By similarity).

Endocytosis of leptin in neuronal cells is needed for hypothalamic leptin signaling and leptin-mediated regulation of feeding and body weight (By similarity). Mediates endocytosis and subsequent lysosomal degradation of CST3 in kidney proximal tubule cells (By similarity).
