Target Background

Function
(From Uniprot)
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 (By similarity)
Gene References into Functions
  1. Leptin was found to stimulate mast cells to degranulation and histamine release. It induced the intracellular Ca(2+) increase, as well. In response to leptin stimulation, mast cells generated and released cysLTs and chemokine CCL3. Leptin-induced upregulation of CYSLTR1 and CYSLTR2 surface expression was observed. It stimulated mast cells to migratory response, even in the absence of extracellular matrix (ECM) proteins. PMID: 30019195
