Enables voltage-gated potassium channel activity. Acts upstream of or within G protein-coupled receptor signaling pathway; potassium ion transport; and regulation of membrane potential. Located in plasma membrane. Part of voltage-gated potassium channel complex. Is expressed in several structures, including brain; early conceptus; limb; olfactory epithelium; and secondary oocyte. Orthologous to human KCNK2 (potassium two pore domain channel subfamily K member 2). [provided by Alliance of Genome Resources, Apr 2022]
