    FAMILY
  • opioids neuropeptides precursors family
  • CATEGORY regulatory
    SUBCELLULAR LOCALIZATION extracellular
        plasma membrane
    text translocation across the plasma membrane may represent a previously unknown mechanism by which dynorphins can signal information to the cell interior
    basic FUNCTION
  • playing a role in Alzheimer disease neuropathology
  • induces calcium influx via voltage-sensitive calcium channels in sensory neurons by activating bradykinin receptors
  • essential role of dynorphin in the termination of seizures
  • activates bradykinin receptors to maintain neuropathic pain
  • regulate pain processing and modulate the rewarding effects of addictive substances
  • acts as a neuromodulator to inhibit ITCH in the dorsal horn of the spinal cord

  • Variant & Polymorphism repeat , other
  • allelic variation at the promoter contributing to prtection against cocaine dependence
  • polymorphisms increasing alcohol dependence
  • functional allelic variants in the PDYN promoter might modify the risk to develop Temporal Lobe Epilepsy (TLE) in subjects with familial predisposition
  • polymorphisms in PDYN are associated with opioid addiction
