MGI Phenotype

FUNCTION: This gene encodes a hypothalamic neuropeptide precursor protein that gives rise to two mature neuropeptides, orexin A and orexin B, by proteolytic processing. Orexin A and orexin B, which bind to orphan G-protein coupled receptors Hcrtr1 and Hcrtr2, function in the regulation of sleep and arousal. This neuropeptide arrangement may also play a role in feeding behavior, metabolism, and homeostasis. [provided by RefSeq, Sep 2015]
PHENOTYPE: Homozygotes for a targeted null mutation exhibit altered sleep patterns, frequent periods of behavioral arrest resembling human narcolepsy, and attenuated morphine dependence. [provided by MGI curators]
