CC   -!- FUNCTION: Neuropeptides that play a significant role in the regulation
CC       of food intake and sleep-wakefulness, possibly by coordinating the
CC       complex behavioral and physiologic responses of these complementary
CC       homeostatic functions. A broader role in the homeostatic regulation of
CC       energy metabolism, autonomic function, hormonal balance and the
CC       regulation of body fluids, is also suggested. Orexin-A binds to both
CC       OX1R and OX2R with a high affinity, whereas orexin-B binds only to OX2R
CC       with a similar high affinity (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Rough endoplasmic reticulum {ECO:0000250}.
CC       Cytoplasmic vesicle {ECO:0000250}. Synapse {ECO:0000250}.
CC       Note=Associated with perikaryal rough endoplasmic reticulum as well as
CC       cytoplasmic large granular vesicles at synapses. {ECO:0000250}.
CC   -!- PTM: Specific enzymatic cleavages at paired basic residues yield the
CC       different active peptides.
CC   -!- SIMILARITY: Belongs to the orexin family. {ECO:0000305}.
