MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene is a G-protein coupled receptor involved in the regulation of feeding behavior. The encoded protein binds the hypothalamic neuropeptides orexin A and orexin B. A related gene (HCRTR1) encodes a G-protein coupled receptor that selectively binds orexin A. [provided by RefSeq, Jan 2009]
PHENOTYPE: Mice bearing targeted mutations in this gene exhibit fragmentation of sleep/wake states with similarity to narcolepsy and rare or very rare episodes of cataplexy. In addition, mice homozygous for a funtionally null allele display enhanced depression-likebehavior. [provided by MGI curators]
