Anti-HCRTR2 antibodies are used in the immunodetection of the protein hypocretin receptor 2. In humans, the canonical protein has a reported length of 444 amino acid residues and a mass of 50.7 kDa. Its subcellular localization is in the cell membrane. It is notably expressed in the cerebellum and cerebral cortex. A member of the G-protein coupled receptor 1 protein family, HCRTR2 is known to be involved with chemical synaptic transmission. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include OX2R, OXR2, orexin receptor type 2, hypocretin (orexin) receptor 2, hypocretin receptor type 2, and ORXR2. HCRTR2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of HCRTR2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
