The κ-opioid receptor (KOR) is a protein that in humans is encoded by the OPRK1 gene. The KOR is one of four related receptors that bind opioid-like compounds in the brain and are responsible for mediating the effects of these compounds. These effects include altering nociception, consciousness, motor control, and mood.
