Predicted to enable transmembrane transporter binding activity and voltage-gated potassium channel activity. Predicted to be involved in potassium ion transmembrane transport and regulation of membrane potential. Predicted to act upstream of or within regulation of G2/M transition of mitotic cell cycle. Predicted to be located in cell surface. Predicted to be integral component of plasma membrane. Is expressed in several structures, including blood vessel; central nervous system; eye; genitourinary system; and thymus. Orthologous to human KCNH5 (potassium voltage-gated channel subfamily H member 5). [provided by Alliance of Genome Resources, Apr 2022]
