CC -!- FUNCTION: Regulatory subunit of multiple voltage-gated sodium channel
CC complexes that play important roles in excitable membranes in brain,
CC heart and skeletal muscle. Enhances the presence of the pore-forming
CC alpha subunit at the cell surface and modulates channel gating
CC characteristics and the rate of channel inactivation. Modulates the
CC activity of a variety of pore-forming alpha subunits, such as SCN1A,
CC SCN2A, SCN3A, SCN4A, SCN5A and SCN10A. {ECO:0000250|UniProtKB:Q00954}.
CC -!- SUBUNIT: Component of a voltage-sensitive sodium channel complex that
CC consists of a pore-forming alpha subunit and one or more regulatory
CC beta subunits. Interacts with SCN4A. Interacts with NFASC. Interacts
CC with SCN10A (By similarity). Interacts with SCN1A. Interacts with
CC SCN3A. Interacts with SCN5A. Interacts with SCN8A (By similarity).
CC {ECO:0000250|UniProtKB:Q00954, ECO:0000250|UniProtKB:Q07699}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:P97952};
CC Single-pass type I membrane protein {ECO:0000250|UniProtKB:Q07699}.
CC Perikaryon {ECO:0000250|UniProtKB:P97952}. Cell projection
CC {ECO:0000250|UniProtKB:P97952}. Cell projection, axon
CC {ECO:0000250|UniProtKB:Q00954}. Note=Detected at nodes of Ranvier on
CC the sciatic nerve. {ECO:0000250|UniProtKB:P97952}.
CC -!- SIMILARITY: Belongs to the sodium channel auxiliary subunit SCN1B (TC
CC 8.A.17) family. {ECO:0000305}.
