Functions
ion channel binding / sodium channel regulator activity / voltage-gated sodium channel activity / voltage-gated sodium channel activity involved in cardiac muscle cell action potential
Processes
atrial cardiac muscle cell action potential / cardiac muscle cell action potential involved in contraction / cardiac muscle contraction / membrane depolarization / membrane depolarization during action potential / membrane depolarization during cardiac muscle cell action potential / nervous system development / positive regulation of heart rate / positive regulation of sodium ion transport / protein localization to plasma membrane / regulation of atrial cardiac muscle cell membrane depolarization / regulation of heart rate by cardiac conduction / regulation of sodium ion transmembrane transporter activity / regulation of ventricular cardiac muscle cell membrane depolarization / SA node cell action potential / sensory perception of pain / sodium ion transmembrane transport / sodium ion transport / ventricular cardiac muscle cell action potential
Components
integral component of membrane / plasma membrane / voltage-gated sodium channel complex / Z disc
General Function
Voltage-gated sodium channel activity involved in cardiac muscle cell action potential
Specific Function
Modulates channel gating kinetics. Causes unique persistent sodium currents. Inactivates the sodium channel opening more slowly than the subunit beta-1. Its association with neurofascin may target the sodium channels to the nodes of Ranvier of developing axons and retain these channels at the nodes in mature myelinated axons (By similarity).
