Gene: SCN4B (sodium voltage-gated channel beta subunit 4) Homo sapiens
Symbol: SCN4B
Name: sodium voltage-gated channel beta subunit 4
Description: Exhibits ion channel binding activity; sodium channel regulator activity; and voltage-gated sodium channel activity involved in cardiac muscle cell action potential. Involved in several processes, including cardiac muscle cell action potential; regulation of heart rate by cardiac conduction; and regulation of ion transport. Localizes to the voltage-gated sodium channel complex. Implicated in long QT syndrome 10.
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: ATFB17; LQT10; Navbeta4; sodium channel beta-4 subunit; sodium channel subunit beta-4; sodium channel, voltage gated, type IV beta subunit; sodium channel, voltage-gated, type IV, beta subunit
