Leptin (from Greek λεπτός leptos, "thin" or "light" or "small"), also known as obese protein, is a protein hormone predominantly made by adipocytes (cells of adipose tissue). Its primary role is likely to regulate long-term energy balance.
OverviewAI-generated
Leptin is a human protein encoded by the LEP gene. The molecule consists of 167 amino acids and has a mass of 18,641. It is associated with obesity, diabetes mellitus, and disease variants. Structural features include disulfide bonds, and its three-dimensional structure has been characterized. Evidence for the protein’s existence is established at the protein level.
The protein is cataloged in UniProt under the accession P41159. It is the subject of 197 clinical trials listed on ClinicalTrials.gov. Additionally, the topic is referenced by 474 other encyclopedia articles.

Key player in the regulation of energy balance and body weight control. Once released into the circulation, has central and peripheral effects by binding LEPR, found in many tissues, which results in the activation of several major signaling pathways (PubMed:15899045, PubMed:17344214, PubMed:19688109). In the hypothalamus, 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…

Leptin (from Greek λεπτός leptos, "thin" or "light" or "small"), also known as obese protein, is a protein hormone predominantly made by adipocytes (cells of adipose tissue). Its primary role is likely to regulate long-term energy balance.
As one of the major signals of energy status, leptin levels influence appetite, satiety, and motivated behaviors oriented toward the maintenance of energy reserves (e.g., feeding, foraging behaviors).
