KCND1, also known as Kv4.1, is a human gene that encodes a voltage-gated potassium channel. It belongs to the Shal-related family of Kv channels and forms A-type potassium channels that activate and inactivate rapidly to help reset the cell membrane after electrical activity. These channels play a key role in regulating neuronal excitability, heart rate, insulin secretion, and other physiological processes.

KCND1 is expressed at moderate levels in many tissues, with lower expression in skeletal muscle. In humans, the gene is located on the X chromosome (Xp11.23). A mouse ortholog is present on the mouse X chromosome, enabling cross-species studies.

This gene is part of the broader voltage-gated potassium channel family, which includes counterparts related to the four Drosophila Shaker-like genes (shaker, shaw, shab, and shal). KCND1 contributes to repolarization of the cell membrane during action potentials and helps shape the electrical signals that control various body functions.
