Disease

KCNC1_HUMAN Progressive myoclonic epilepsy type 7. The disease is caused by variants affecting the gene represented in this entry.

Function

KCNC1_HUMAN Voltage-gated potassium channel that plays an important role in the rapid repolarization of fast-firing brain neurons. The channel opens in response to the voltage difference across the membrane, forming a potassium-selective channel through which potassium ions pass in accordance with their electrochemical gradient (PubMed:25401298). Can form functional homotetrameric channels and heterotetrameric channels that contain variable proportions of KCNC2, and possibly other family members as well. Contributes to fire sustained trains of very brief action potentials at high frequency in pallidal neurons.[UniProtKB:P25122]^[1]
