Anti-Leptin Receptor

In 1X PBS, pH 7.4, with 0.09% sodium azide. Leptin, an adipocyte-specific hormone, regulates adipose-tissue mass through hypothalamic effects on satiety and energy expenditure by acting through the leptin receptor (LEPR). LEPR is a single-transmembrane-domain receptor of the cytokine receptor family that is identical to the mouse diabetes (db) gene product. During weight loss, leptin levels decrease, whereas soluble LEPR levels and the receptor bound fraction of leptin increases. The presence of LEPR in the absorptive cells of the small intestine suggests that leptin may have a physiological role in the regulation of nutrient absorption. Protein function: Receptor for obesity factor (leptin). On ligand binding, mediates signaling through JAK2/STAT3. Involved in the regulation of fat metabolism and, in a hematopoietic pathway, required for normal lymphopoiesis. May play a role in reproduction. Can also mediate the ERK/FOS signaling pathway.
