- Description
- Predicted to enable voltage-gated potassium channel activity. Predicted to be involved in action potential and potassium ion transmembrane transport. Predicted to act upstream of or within potassium ion transport and transmembrane transport. Predicted to be part of voltage-gated potassium channel complex. Predicted to be active in membrane. Is expressed in central nervous system; heart; and inner ear. Human ortholog(s) of this gene implicated in benign neonatal seizures and developmental and epileptic encephalopathy 7. Orthologous to human KCNQ2 (potassium voltage-gated channel subfamily Q member 2).
