InnateDB Gene IDBG-192481 (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.
Disease Associations
Tissue Specificity Widely expressed. {ECO:0000269PubMed:15256537}.
