Description: Investigation of VAP33 as a novel mu-opioid receptor interacting protein

Opioid drugs (i.e. morphine, fentanyl, oxycodone) are the most effective analgesics clinically available for treating moderate to severe pain. The chronic use of opioids, however, poses the risk of tolerance, physical dependence and addiction. The molecular changes that occur in the central nervous system in response to chronic opioid exposure remain unclear. The goal of my research is to characterize novel protein-protein interactions at the key opioid receptor that contributes to drug tolerance and addiction. I am currently analyzing the interaction between the mu-opioid receptor (MOR) and its interacting protein partner VAP33. Understanding the functional significance of the MOR/VAP33 interaction will help to elucidate the molecular basis for neuronal changes that occur in response to morphine and other opioid drugs.
