Enables sodium channel regulator activity. Involved in regulation of voltage-gated sodium channel activity and response to pyrethroid. Located in node of Ranvier and plasma membrane. Part of voltage-gated sodium channel complex. Biomarker of type 2 diabetes mellitus. Human ortholog(s) of this gene implicated in Brugada syndrome 5; developmental and epileptic encephalopathy 52; familial atrial fibrillation; and generalized epilepsy with febrile seizures plus 1. Orthologous to human SCN1B (sodium voltage-gated channel beta subunit 1); PARTICIPATES IN alfentanil pharmacodynamics pathway; bupivacaine pharmacodynamics pathway; buprenorphine pharmacodynamics pathway; INTERACTS WITH (+)-trans-(S)-allethrin; 17beta-estradiol; 2,2',4,4'-Tetrabromodiphenyl ether.

bioallethrin affects the reaction [[SCN2B protein co-treated with SCN1B protein co-treated with SCN8A protein mutant form] results in increased transport of Sodium]
cypermethrin affects the reaction [[SCN2A protein binds to SCN1B protein] which results in increased transport of Sodium] and SCN1B protein promotes the reaction [cypermethrin binds to SCN2A protein]
Tetrodotoxin results in decreased activity of [SCN2A protein binds to SCN1B protein] and Tetrodotoxin results in decreased activity of [SCN8A protein binds to SCN1B protein binds to SCN2B protein]
