endorphin receptor or opioid receptor

Function

• endorphin or opioid receptors are coupled to Gi
• the opioid receptors also mediate effects on Ca+2 channel & K+ channel activity

Expression

• areas of the brain rich in opioid receptors include:
  • rostral anterior cingulate cortex
  • lower brainstem

More general terms

• G-protein coupled receptor; serpentine receptor
• synaptic receptor

More specific terms

• delta opioid receptor; DOR-1 (OPRD1, OPRD)
• kappa opioid receptor; KOR-1 (OPRK1 OPRK)
• mu opioid receptor; MOR-1 (OPRM1, MOR1)
• nociceptin receptor; orphanin FQ receptor; kappa-type 3 opioid receptor; KOR-3 (OPRL1 OOR ORL1)
• opioid growth factor receptor (opioid growth factor receptor, OGFr, 7-60 protein)
• opioid sigma receptor
• probable opioid receptor ORL1

Additional terms

• brainstem
• cingulate gyrus; gyrus cinguli; cingulate cortex
• endorphin
