Orexin-A (OR-A) and orexin-B (OR-B) play an important role in the regulation of energy balance and the control of sleep-wake cycle. They act via G-protein coupled receptors, namely orexin receptor-1 (OX1R) and orexin receptor-2 (OX2R). OX2R has equal affinity for both OR-A and OR-B, whilst OX1R has a 10-fold greater affinity for OR-A. Orexin-mediated functions have been extensively explored, however, the intracellular signalling pathways remain poorly understood. Using HEK-293...
