Gene Name
| KCNN4 |
Protein Type
| Transporter |
Biological Properties |
General Function
| Involved in calmodulin binding |
Specific Function
| Forms a voltage-independent potassium channel that is activated by intracellular calcium. Activation is followed by membrane hyperpolarization which promotes calcium influx. The channel is blocked by clotrimazole and charybdotoxin but is insensitive to apamin |
