Protein Structure
UniProt Annotation
Function Orphan receptor. Probably involved in the function of nociceptive neurons. May regulate nociceptor function and/or development, including the sensation or modulation of pain. Potently activated by enkephalins including BAM22 (bovine adrenal medulla peptide 22) and BAM (8-22). BAM22 is the most potent compound and evoked a large and dose-dependent release of intracellular calcium in stably transfected cells. G(alpha)q proteins are involved in the calcium-signaling pathway. Activated by the antimalarial drug, chloroquine. May mediate chloroquine- induced itch, in a histamine-independent manner. {ECO:0000269PubMed:11850634, ECO:0000269PubMed:20004959}.
Subcellular Localization Cell membrane; Multi-pass membrane protein.
Disease Associations
Tissue Specificity Uniquely localized in a subset of small dorsal root and trigeminal sensory neurons. {ECO:0000269PubMed:11850634}.
