Gene Symbol HCRTR1
Protein Name hypocretin (orexin) receptor 1
Synonyms OX1R;
Species Homo sapiens
Ensembl Protein ENSP00000384387
InnateDB Gene IDBG-95458 (HCRTR1)
Protein Structure
UniProt Annotation
Function Moderately selective excitatory receptor for orexin-A and, with a lower affinity, for orexin-B neuropeptide. Seems to be exclusively coupled to the G(q) subclass of heteromeric G proteins, which activates the phospholipase C mediated signaling cascade (By similarity). {ECO:0000250}.
Subcellular Localization Cell membrane; Multi-pass membrane protein.
