Predicted to enable RNA polymerase II cis-regulatory region sequence-specific DNA binding activity and voltage-gated potassium channel activity. Predicted to be involved in negative regulation of apoptotic process; potassium ion transmembrane transport; and regulation of membrane potential. Predicted to act upstream of or within ion transport and regulation of ion transmembrane transport. Predicted to be located in plasma membrane. Predicted to be integral component of plasma membrane. Orthologous to human KCNH8 (potassium voltage-gated channel subfamily H member 8). [provided by Alliance of Genome Resources, Apr 2022]
