Subcellular LocationCell membrane; Single-pass type I membrane protein. Isoform E- Secreted (Probable)
Developmental StageNA
SimilarityBelongs to the type I cytokine receptor family. Type 2 subfamily. Contains 4 fibronectin type-III domains. Contains 1 Ig-like (immunoglobulin-like) domain.
Post Translational ModificationOn ligand binding; phosphorylated on two conserved C-terminal tyrosine residues (isoform B only) by JAK2. Tyr-985 is required for complete binding and activation of PTPN11; ERK/FOS activation and; for interaction with SOCS3. Phosphorylation on Tyr-1138 is required for STAT3 binding/activation. Phosphorylation of Tyr-985 is required for SOCS3 binding and SOCS3 mediated inhibition of leptin signaling; whereas phosphorylation of Tyr-1077 has a more accessory role.
FunctionReceptor 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. Isoform A may act to transport leptin to the cerebrospinal fluid. Isoform E could function as a transport protein.
