| Name
| Potassium voltage-gated channel subfamily KQT member 3 |
| Description
| Not Available |
| Synonyms
|
- KQT-like 3
- Potassium channel subunit alpha KvLQT3
- Voltage-gated potassium channel subunit Kv7.3

| Gene Name
| KCNQ3 |
| Protein Type
| Transporter |
| Biological Properties |
|---|
| General Function
| Involved in potassium channel activity |
| Specific Function
| Probably important in the regulation of neuronal excitability. Associates with KCNQ2 or KCNQ5 to form a potassium channel with essentially identical properties to the channel underlying the native M-current, a slowly activating and deactivating potassium conductance which plays a critical role in determining the subthreshold electrical excitability of neurons as well as the responsiveness to synaptic inputs |
