How to apply Kv4.3 in biological research?

Potassium voltage-gated channel subfamily D member 3 (Kv4.3 ) is a protein that in humans is encoded by the KCND3 gene. It contributes to the cardiac transient outward potassium current (Ito1), the main contributing current to the repolarizing phase 1 of the cardiac action potential. Kv4.3 is a member of the Shal family of Kv channels and generates a rapidly activating and rapidly inactivating current, contributing to the transient outward K+ current in the heart.
