General annotation (Comments)
| Function | This protein 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. It is a tetrodotoxin-resistant sodium channel isoform. Its electrophysiological properties vary depending on the type of the associated beta regulatory auxiliary subunits (in vitro). Plays a role in neuropathic pain mechanisms. Ref.1 Ref.2 Ref.9 |
| Subunit structure | The voltage-resistant sodium channel consists of an ion conducting pore forming alpha-subunit regulated by one or more associated auxiliary subunits SCN1B, SCN2B and SCN3B. Found in a number of complexes with PRX, DYNLT1 and PDZD2. Interacts with proteins such as FSTL1, PRX, DYNLT1, PDZD2, S100A10 and many others. Interacts with NEDD4 and NEDD4L. Ref.3 Ref.7 Ref.8 |
| Subcellular location | Membrane; Multi-pass membrane protein By similarity. Note: It can be translocated to the extracellular membrane through association with S100A10. Ref.7 |
| Tissue specificity | Expressed in dorsal root ganglia, trigeminal ganglia, nodose ganglia and sciatic nerve. Ref.1 Ref.2 Ref.6 |
| Developmental stage | Expressed in dorsal root ganglia at 15 dpc onwards. Ref.6 |
| Induction | Down-regulated after axotomy in dorsal root ganglia. Ref.5 |
| 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 modification | Ubiquitinated by NEDD4L; which promotes its endocytosis By similarity. |
| Sequence similarities | Belongs to the sodium channel (TC 1.A.1.10) family. Nav1.8/SCN10A subfamily. [View classification] Contains 1 IQ domain. |
