    SUBCELLULAR LOCALIZATION     plasma membrane
    basic FUNCTION
  • voltage-gated, type X,tetrodotoxin resistant, specific to sensory neurons
  • mediates the voltage-dependent sodium ion permeability of excitable membranes
  • contributes a substantial fraction of the current underlying the depolarizing phase of the action potential of dorsal root ganglion (DRG) neurons
  • plays a role in neuropathic pain mechanisms
  • have a central role in the propagation of action potentials in nociceptive nerve fibers
  • may play a role in different pain conditions, and its signaling might be involved in visceral pain
  • modulatory role in the development of cold, but not mechanical allodynia in neuropathic pain conditions
  • function in the transmission of pain signals induced by cold, heat, and mechanical stimuli
  • implicated in modulating the activity of CNS neurons
  • implicated in transducing pain initiated by cold and additionally implicate SCN10A in previously unknown functions in the central nervous system and heart
