Gene Name
| KCNA4 |
Protein Type
| Enzyme |
Biological Properties |
General Function
| Involved in protein binding |
Specific Function
| Mediates the voltage-dependent potassium ion permeability of excitable membranes. Assuming opened or closed conformations in response to the voltage difference across the membrane, the protein forms a potassium-selective channel through which potassium ions may pass in accordance with their electrochemical gradient |
