  • Function
    Tetrodotoxin-resistant channel that mediates the voltage-dependent sodium ion permeability of excitable membranes. Assuming opened or closed conformations in response to the voltage difference across the membrane, the protein forms a sodium-selective channel through which sodium ions may pass in accordance with their electrochemical gradient. Plays a role in neuropathic pain mechanisms.
  • Tissue specificity
    Expressed in the dorsal root ganglia and sciatic nerve.
  • Involvement in disease
    Episodic pain syndrome, familial, 2
  • Sequence similarities
    Belongs to the sodium channel (TC 1.A.1.10) family. Nav1.8/SCN10A subfamily.
    Contains 1 IQ domain.
  • Domain
    The sequence contains 4 internal repeats, each with 5 hydrophobic segments (S1,S2,S3,S5,S6) and one positively charged segment (S4). Segments S4 are probably the voltage-sensors and are characterized by a series of positively charged amino acids at every third position.
  • Post-translational
    Ubiquitinated by NEDD4L; which promotes its endocytosis.
    Phosphorylation at Ser-1451 by PKC in a highly conserved cytoplasmic loop slows inactivation of the sodium channel and reduces peak sodium currents.
  • Cellular localization
    Cell membrane. It can be translocated to the cell membrane through association with S100A10.

  • Western blot analysis. A single band of strong NaV1.8-like immunoreactivity at approximately 240 kDa in the membrane fraction of rat DRG is shown. Note that membrane fractions of rat whole brain, cerebellum, skeletal muscle, heart, superior cervical ganglia, liver and kidney showed no detectable immunoreactivity. Membrane extract from CHO-SNS22 (a cell line stably transfected with rat NaV1.8 cDNA) showed strong immunoreactivity at the same size with DRG. Non-transfected CHO cells did not show any bands.
  • Immunohistochemistry was performed on 2 week old rat lumber DRG sections. NaV1.8-like immunoreactivity can be detected only in small diameter (<30 um) neurons.
