Overview
Mermaid diagram (expand to render)
KCNC1 (Potassium Voltage-Gated Channel Subfamily C Member 1) encodes the Kv3.1 potassium channel, a high-threshold, fast-activating, and fast-deactivating voltage-gated potassium channel. Kv3.1 is critical for high-frequency neuronal firing and is prominently expressed in fast-spiking interneurons.
Normal Function
KCNC1/Kv3.1 functions as:
Voltage-gated potassium channel: Permits K+ efflux during action potential repolarization
High-frequency firing regulator: Enables [neurons](/entities/neurons) to fire at high frequencies (up to 800 Hz)
Fast-spiking interneuron marker: Characteristic of parvalbumin-positive interneurons
Neural circuit optimization: Improves temporal precision in auditory and hippocampal circuits
Biophysical Properties
Kv3.1 channels are characterized by:
High activation threshold: Activates at potentials above -10 mV
Fast deactivation: Rapid return to closed state
High conductance: Large K+ currents
Voltage-dependent activation: Requires depolarization for opening
Gene Structure
The KCNC1 gene is located on chromosome 11p15.5 and encodes a 512-amino acid transmembrane protein with six alpha-helical segments (S1-S6) and a pore loop.
Disease Associations
Epilepsy
KCNC1 mutations cause progressive myoclonus epilepsy (EPM7)
Channel dysfunction leads to hyperexcitability
Affected neurons cannot fire at high frequencies properly
