CC   -!- FUNCTION: Mediates the voltage-dependent sodium ion permeability of
CC       excitable membranes. Assuming opened or closed conformations in
CC       response to the voltage difference across the membrane, the protein
CC       forms a sodium-selective channel through which Na(+) ions may pass in
CC       accordance with their electrochemical gradient (PubMed:15123669). It is
CC       a tetrodotoxin-sensitive Na(+) channel isoform. Plays a role in pain
CC       mechanisms, especially in the development of inflammatory pain
CC       (PubMed:15314237). {ECO:0000250|UniProtKB:Q15858,
CC       ECO:0000269|PubMed:15123669, ECO:0000269|PubMed:15314237}.
CC   -!- SUBUNIT: The sodium channel complex consists of a large, channel-
CC       forming alpha subunit (SCN9A) regulated by one or more beta subunits
CC       (SCN1B, SCN2B, SCN3B and SCN4B) (By similarity). SCN1B and SCN3B are
CC       non-covalently associated with SCN2A. SCN2B and SCN4B are disulfide-
CC       linked to SCN2A (By similarity). Interacts with NEDD4 and NEDD4L.
CC       Interacts with the conotoxin GVIIJ (By similarity).
CC       {ECO:0000250|UniProtKB:O08562, ECO:0000250|UniProtKB:Q15858,
CC       ECO:0000269|PubMed:15123669}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000269|PubMed:15123669};
CC       Multi-pass membrane protein {ECO:0000250|UniProtKB:D0E0C2}. Cell
CC       projection, neuron projection {ECO:0000250|UniProtKB:O08562}. Note=In
CC       neurite terminals. {ECO:0000250|UniProtKB:O08562}.
CC   -!- TISSUE SPECIFICITY: Expressed strongly in sciatic nerves, with moderate
CC       levels in kidney (PubMed:31647222). Not detected in liver, brain and
CC       muscle (PubMed:31647222). {ECO:0000269|PubMed:31647222}.
CC   -!- DOMAIN: The sequence contains 4 internal repeats, each with 5
CC       hydrophobic segments (S1, S2, S3, S5, S6) and one positively charged
CC       segment (S4). Segments S4 are probably the voltage-sensors and are
CC       characterized by a series of positively charged amino acids at every
CC       third position. {ECO:0000305}.
CC   -!- PTM: Ubiquitinated by NEDD4L; which may promote its endocytosis. Does
CC       not seem to be ubiquitinated by NEDD4. {ECO:0000269|PubMed:15123669}.
CC   -!- PTM: Phosphorylation at Ser-1488 by PKC in a highly conserved
CC       cytoplasmic loop increases peak sodium currents.
CC       {ECO:0000250|UniProtKB:Q15858}.
CC   -!- SIMILARITY: Belongs to the sodium channel (TC 1.A.1.10) family.
CC       Nav1.7/SCN9A subfamily. {ECO:0000305}.
