Summaries for HCRTR1 Gene

Entrez Gene Summary for HCRTR1 Gene

  • The protein encoded by this gene is a G-protein coupled receptor involved in the regulation of feeding behavior. The encoded protein selectively binds the hypothalamic neuropeptide orexin A. A related gene (HCRTR2) encodes a G-protein coupled receptor that binds orexin A and orexin B. [provided by RefSeq, Jan 2009]

GeneCards Summary for HCRTR1 Gene

HCRTR1 (Hypocretin (Orexin) Receptor 1) is a Protein Coding gene. Diseases associated with HCRTR1 include hallucinogen dependence and narcolepsy. Among its related pathways are Signaling by GPCR and Interleukin receptor SHC signaling. GO annotations related to this gene include G-protein coupled receptor activity and peptide hormone binding. An important paralog of this gene is NPFFR1.

UniProtKB/Swiss-Prot for HCRTR1 Gene

  • 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).

Tocris Summary for HCRTR1 Gene

  • The OX1 receptors, also known as hypocretin receptor 1, are located primarily in the ventromedial hypothalamus, locus coeruleus, median raphe, hippocampus and taenia tecta where they are thought to regulate sleep-wakefulness and energy homeostasis, particularly food intake.
