KCNA7
Description
The KCNA7 (potassium voltage-gated channel subfamily A member 7) is a protein-coding gene located on chromosome 19.
KCNA7, also known as Kv1.7, is a protein encoded by the KCNA7 gene in humans. This protein acts as a subunit of a voltage-gated potassium channel. It is believed to contribute to the transient outward potassium current (Ito1) in the heart, playing a role in the repolarization phase 1 of the cardiac action potential.
KCNA7 plays a crucial role in regulating the movement of potassium ions across the membranes of excitable cells, such as nerve and muscle cells. It does this by forming a channel that allows potassium ions to pass through the membrane in response to changes in the electrical potential across the membrane. This channel opens and closes based on the voltage difference across the membrane, ensuring that potassium ions flow in accordance with their electrochemical gradient.
KCNA7 is also known as HAK6, KV1.7.
