    SUBCELLULAR LOCALIZATION     plasma membrane
    text
  • SCN11A protein is preferentially localized in axons and growth cones
  • basic FUNCTION
  • sodium channel voltage-gated resistant to tetrodoxin
  • mediating brain-derived neurotrophic factor (BDNF)-evoked membrane depolarization through the receptor tyrosine kinase NTRK2
  • its sodium channel provides an important link between inflammatory processes and changes in urodynamic properties that occur during urinary bladder inflammation (Ritter 2009)
  • may play a role in different pain conditions, and its signaling might be involved in visceral pain (Leo 2010)
  • modulatory role in the development of cold, but not mechanical allodynia in neuropathic pain conditions (Leo 2010)
  • plays a crucial role in the generation of heat and mechanical pain hypersensitivity, both in subacute and chronic inflammatory pain models
  • its function appears to be essential for activity-dependent axon growth, acting upstream of spontaneous Ca(2+) elevation through voltage-gated calcium channels (VGCCs)
  • contributes to expression of persistent Na current in small diameter, nociceptive sensory neurons in dorsal root ganglia and is required for inflammatory pain sensation

    would be an appealing target for the development of specific drugs to relieve pain

    activation could therefore serve as a target for modulating axonal regeneration in motoneuron diseases such as SMA in which presynaptic activity of VGCCs is reduced
    ANIMAL & CELL MODELS
  • in Nav1.9-null mice, although the Nav1.9 channel does not contribute to basal pain thresholds, it plays an important role in heat pain hypersensitivity induced by subacute paw inflammation
