Product Detail	Leptin, the product of the ob (obese) gene, is a 16kD protein consisting of 146 amino acid residues. Leptin is produced in the adipose tissue, and is considered to play an important role in appetite control, fat metabolism and regulation of body weight. It targets the central nervous system, particularly hypothalamus, affecting food intake. Leptin levels are high in most obese individuals. Studies have shown that it may also influence reproductive function. Function: May function as part of a signaling pathway that acts to regulate the size of the body fat depot. An increase in the level of LEP may act directly or indirectly on the CNS to inhibit food intake and/or regulate energy expenditure as part of a homeostatic mechanism to maintain constancy of the adipose mass. Subunit: Interacts with SIGLEC6. Subcellular Location: Secreted. DISEASE: Leptin deficiency (LEPD) [MIM:614962]: A rare disease characterized by low levels of serum leptin, severe hyperphagia and intractable obesity from an early age. Note=The disease is caused by mutations affecting the gene represented in this entry. SWISS: P50595 Gene ID: 3952 Database links: Entrez Gene: 3952 Human Entrez Gene: 16846 Mouse Entrez Gene: 25608 Rat Omim: 164160 Human SwissProt: P41159 Human SwissProt: P41160 Mouse SwissProt: Q29406 Pig SwissProt: P50596 Rat SwissProt: Q28603 Sheep Unigene: 194236 Human Unigene: 277072 Mouse Unigene: 44444 Rat Leptin是一种分子量为16kDa的脂肪组织源激素，又称：肥胖蛋白(Obese-protein)是由脂肪细胞分泌的，具有强亲水性，以单体形式存在于血浆中。 Leptin 具有广泛的生物学效应，作用于下丘脑，调节食欲、能量代谢及体重。Leptin 还可能作为脂肪-胰岛内分泌轴的一部分，参与胰岛素分泌的调节。
