Orexin R2/HCRTR2 in Human Brain. Orexin R2/HCRTR2 was detected in immersion fixed paraffin-embedded sections of human brain (hypothalamus) using 25 µg/mL Mouse Anti-Human Orexin R2/HCRTR2 Monoclonal Antibody (Catalog # MAB52461) overnight at 4 °C. Tissue was stained with the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue).

Background: Orexin R2/HCRTR2
Orexin R2 (Orexin Receptor 2), also known as HCRTR2 (Hypocretin Receptor 2) or OX2R is a 40 kDa 7-transmembrane G-protein-coupled glycoprotein that is a high affinity receptor for orexins A and B (hypocretins 1 and 2). In mouse brain, engagement of Orexin Rs/HCRTRs promotes wakefulness, such that absence of either orexins or their receptors creates a narcolepsy-like state. It also influences reward circuits involving food or addictive drugs. The extracellular portions of human Orexin R2/HCRTR2 share 92% and 93% aa identity with corresponding portions of mouse and rat Orexin R2/HCRTR2, respectively.
