Mouse Leptin Receptor (LEPR) Protein

Background

The leptin receptor (LEPR) is a cell surface receptor that plays a central role in energy homeostasis, metabolism, and body weight regulation. LEPR is the receptor for leptin, a hormone primarily secreted by adipose (fat) tissue that signals satiety and energy sufficiency to the brain. Leptin and its receptor are fundamental to regulating food intake, body weight, and energy expenditure. When leptin binds to LEPR, it triggers a cascade of intracellular signals that inform the central nervous system about the body's energy reserves, particularly in the hypothalamus, which then influences appetite suppression, metabolism, and other endocrine functions. LEPR is essential in maintaining homeostatic control over body mass, as dysregulation or mutations in the leptin receptor pathway can lead to obesity, diabetes, and metabolic syndrome.
