Predicted to enable delayed rectifier potassium channel activity. Predicted to be involved in potassium ion transmembrane transport. Predicted to act upstream of or within potassium ion transport. Predicted to be located in endoplasmic reticulum and plasma membrane. Predicted to be part of voltage-gated potassium channel complex. Predicted to be integral component of membrane. Is expressed in diencephalon lateral wall mantle layer; hypothalamus mantle layer; lung; and midbrain mantle layer. Orthologous to human KCNG3 (potassium voltage-gated channel modifier subfamily G member 3). [provided by Alliance of Genome Resources, Apr 2022]
