CC -!- FUNCTION: Inhibits neurotransmitter release by reducing calcium CC ion currents and increasing potassium ion conductance. Receptor CC for beta-endorphin. CC -!- SUBUNIT: Forms a complex with G(alpha)z/i2 subunits and the RGSZ CC proteins, RGSZ17 and RGSZ20. The formation of this complex results CC in mu-opioid receptor desensitization. Interacts with RGSZ17 and CC RGSZ20 (By similarity). CC -!- SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein. CC -!- TISSUE SPECIFICITY: Brain. Is expressed in the cerebral cortex, CC caudate putamen, nucleus accumbens, septal nuclei, thalamus, CC hippocampus, and habenula. Not detected in cerebellum. CC -!- SIMILARITY: Belongs to the G-protein coupled receptor 1 family.
