Previous GeneCards Identifiers for LEPR Gene
The protein encoded by this gene belongs to the gp130 family of cytokine receptors that are known to stimulate gene transcription via activation of cytosolic STAT proteins. This protein is a receptor for leptin (an adipocyte-specific hormone that regulates body weight), and is involved in the regulation of fat metabolism, as well as in a novel hematopoietic pathway that is required for normal lymphopoiesis. Mutations in this gene have been associated with obesity and pituitary dysfunction. Alternatively spliced transcript variants encoding different isoforms have been described for this gene. It is noteworthy that this gene and LEPROT gene (GeneID:54741) share the same promoter and the first 2 exons, however, encode distinct proteins (PMID:9207021).[provided by RefSeq, Nov 2010]
GeneCards Summary for LEPR Gene
LEPR (Leptin Receptor) is a Protein Coding gene. Diseases associated with LEPR include obesity, morbid, due to leptin receptor deficiency and leptin deficiency. Among its related pathways are Signaling by GPCR and Interleukin receptor SHC signaling. GO annotations related to this gene include identical protein binding and cytokine receptor activity.
UniProtKB/Swiss-Prot for LEPR Gene
Receptor for obesity factor (leptin). On ligand binding, mediates signaling through JAK2/STAT3. Involved in the regulation of fat metabolism and, in a hematopoietic pathway, required for normal lymphopoiesis. May play a role in reproduction. Can also mediate the ERK/FOS signaling pathway (By similarity).
Leptin was initially thought to have a role in energy homeostasis and obesity. It acts via leptin receptors (Ob-Rs), which are transmembrane catalytic receptors found on NPY/AgRP and alpha-MSH/CART neurons in hypothalamic nuclei. There are six isoforms of Ob-R.
