UniProtKB description: Inhibitor of voltage-gated potassium channels of the Kv4/KCND family. Inhibition of Kv4.3/KCND3 and Kv4.2/KCND2 is strongly voltage-dependent, while inhibition of Kv4.1/KCND1 shows less voltage-dependence. Its binding site may be near the potassium channel voltage sensor. Also blocks calcium channels.
