Description

Exhibits voltage-gated potassium channel activity. Involved in hindbrain formation and somitogenesis. Predicted to localize to integral component of plasma membrane. Human ortholog(s) of this gene implicated in colorectal adenocarcinoma. Is expressed in gill; nervous system; pleuroperitoneal region; and trunk. Orthologous to human KCNH1 (potassium voltage-gated channel subfamily H member 1).
