Background Information

The hormone leptin, secreted predominantly from adipose tissue, plays a crucial role in the regulation of numerous neuroendocrine functions, from energy homeostasis to reproduction (PMID: 22249808). Leptin acts through the leptin receptor (LEPR, also known as OB-R), a single-transmembrane-domain receptor of the cytokine receptor family. On ligand binding, LEPR mediates signaling through JAK2/STAT3 (PMID: 9102398). LEPR plays an important role in the regulation of glucose homeostasis via feeding and adiposity. Alternatively spliced transcript variants encoding different isoforms of LEPR have been described. This antibody can recognize long (LEPRb) and short (LEPRa,c,d) isoforms. This antibody detects endogenous LEPR with an apparent molecular weight of 150 kDa, which is larger than the predicted molecular weight, probably due to glycosylation (PMID: 10026237).
