Potassium voltage-gated channel subfamily D member 3 also known as K_v4.3 is a protein that in humans is encoded by the KCND3 gene.^[5]^[6]^[7] It contributes to the cardiac transient outward potassium current (I_to1), the main contributing current to the repolarizing phase 1 of the cardiac action potential.^[8]
