Previous GeneCards Identifiers for HCRTR2 Gene
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]
GeneCards Summary for HCRTR2 Gene
HCRTR2 (Hypocretin Receptor 2) is a Protein Coding gene. Diseases associated with HCRTR2 include cluster headache and narcolepsy. Among its related pathways are Peptide ligand-binding receptors and Interleukin-3, 5 and GM-CSF signaling. GO annotations related to this gene include G-protein coupled receptor activity and peptide hormone binding. An important paralog of this gene is NPY1R.
UniProtKB/Swiss-Prot for HCRTR2 Gene
Nonselective, high-affinity receptor for both orexin-A and orexin-B neuropeptides.
The OX2 receptors, also known as hypocretin receptor 2, are located primarily in the cerebral cortex, paraventricular hypothalamus, nucleus accumbens, subthalamic and paraventricular thalamus where they are thought to regulate sleep-wakefulness.
