RC TISSUE=Hypothalamus; RX MEDLINE=98150861; PubMed=9491897; DOI=10.1016/S0092-8674(00)80949-6; RA Sakurai T., Amemiya A., Ishii M., Matsuzaki I., Chemelli R.M., RA Tanaka H., Williams S.C., Richardson J.A., Kozlowski G.P., Wilson S., RA Arch J.R.S., Buckingham R.E., Haynes A.C., Carr S.A., Annan R.S., RA McNulty D.E., Liu W.-S., Terrett J.A., Elshourbagy N.A., Bergsma D.J., RA Yanagisawa M.; RT "Orexins and orexin receptors: a family of hypothalamic neuropeptides RT and G protein-coupled receptors that regulate feeding behavior."; RL Cell 92:573-585(1998). CC -!- FUNCTION: Neuropeptides that play a significant role in the CC regulation of food intake and sleep-wakefulness, possibly by CC coordinating the complex behavioral and physiologic responses of CC these complementary homeostatic functions. A broader role in the CC homeostatic regulation of energy metabolism, autonomic function, CC hormonal balance and the regulation of body fluids, is also CC suggested. Orexin-A binds to both OX1R and OX2R with a high CC affinity, whereas orexin-B binds only to OX2R with a similar high CC affinity (By similarity). CC -!- SUBCELLULAR LOCATION: Rough endoplasmic reticulum (By similarity). CC Cytoplasmic vesicle (By similarity). Cell junction, synapse (By CC similarity). Note=Associated with perikaryal rough endoplasmic CC reticulum as well as cytoplasmic large granular vesicles at CC synapses (By similarity). CC -!- SIMILARITY: Belongs to the orexin family.
