General FunctionPhosphorelay sensor kinase activity
Specific FunctionPore-forming (alpha) subunit of a voltage-gated delayed rectifier potassium channel (PubMed:22732247). Channel properties may be modulated by subunit assembly, but not by cyclic nucleotides (By similarity). Mediates IK(NI) current in myoblasts (PubMed:9738473). Involved in the regulation of cell proliferation and differentiation, in particular adipogenic and osteogenic differentiation in bone marrow-derived mesenchymal stem cells (MSCs) (PubMed:23881642).
