CD295, OBR (OB receptor), or LEPR (leptin receptor) is a single pass type I transmembrane glycoprotein of the type I cytokine receptor family, type 2 subfamily.  LEPR has an extracellular region with 4 fibronectin type III (FN3) domains, 1 Immunoglobulin (Ig)-like domain, and a juxtamembrane WSXWS motif, a transmembrane domain (TM), and a cytoplasmic tail with a box 1 motif.  The WSXWS motif is necessary for proper protein folding and efficient intracellular transport and cell-surface receptor binding, while the box 1 motif is required for JAK interaction and activation. LEPR acts as a receptor for leptin (an adipocyte-specific hormone that regulates body weight), and is involved in the regulation of fat metabolism, as well as in a novel hematopoietic pathway that is required for normal lymphopoiesis. Upon ligand binding, LEPR mediates leptin central and peripheral effects through the activation of different signaling pathways such as JAK2/STAT3 and MAPK cascade. In the hypothalamus, leptin acts as an appetite-regulating factor that induces a decrease in food intake and an increase in energy consumption by inducing anorexinogenic factors and suppressing orexigenic neuropeptides, also regulates bone mass and secretion of hypothalamo-pituitary-adrenal hormones. In the periphery, leptin increases basal metabolism, influences reproductive function, regulates pancreatic beta-cell function and insulin secretion, is pro-angiogenic and affects innate and adaptive immunity. LEPR has a specific effect on T lymphocyte responses, differentially regulating the proliferation of naive and memory T -ells. Leptin increases Th1 and suppresses Th2 cytokine production. Mutations in the LEPR gene are associated with obesity and pituitary dysfunction.
