UniProtKB - O97661 (OX1R_PIG)
Protein
Orexin/Hypocretin receptor type 1
Gene
HCRTR1
Organism
Sus scrofa (Pig)
Status
Functioni
Moderately selective excitatory receptor for orexin-A and, with a lower affinity, for orexin-B neuropeptide. Triggers an increase in cytoplasmic Ca2+ levels in response to orexin-A binding.
