OPRL1 - Nociceptin receptor
Order number: 71091
Description
We are excited to introduce our off-the-shelf, full-length, active, and native Nociceptin receptor (OPRL1). OPRL1
is a G-protein coupled opioid receptor that binds to the neuropeptide nociceptin to modulate pain signalling, stress responses, and emotional behaviour. Its clinical relevance is in neuropsychiatry and addiction medicine and can be a key target for treating chronic pain, anxiety disorders, and substance abuse.

| Function | G-protein coupled receptor that binds the endogenous peptide nociceptin/orphanin FQ to modulate complex processes like pain signaling, anxiety, and reward. Therapeutically, it is a significant target for developing "non-mu" analgesics and treatments for substance use disorders, as its activation can oppose the addictive effects of traditional opioids while providing pain relief with a lower risk of respiratory depression. |
