2-41 8.12e-06

Obesity receptor immunoglobulin like domain; This is the immunoglobulin-like domain (IGD) found in obesity receptors (ObR). ObR is a single membrane-spanning receptor belonging to the class I cytokine receptor family. All isoforms have an identical extracellular part consisting of six domains: an N-terminal domain (NTD), two CRH domains (CRH1 and CRH2), an immunoglobulin-like domain (IGD), and two additional membrane-proximal fibronectin type III (FN III) domains. ObR activation depends on the CRH2, IGD, and FN III domains, however the CRH2 domain is the major leptin-binding determinant in the receptor. The IGD and membrane-proximal domains have no detectable affinity for the ligand, but are nonetheless indispensable for receptor activation. Deletion of the IGD results in a receptor with wild-type affinity for leptin, but completely devoid of biological activity.
