UniProtKB description: Pore-forming (alpha) subunit of a voltage-gated delayed rectifier potassium channel that mediates outward-rectifying potassium currents which, on depolarization, reaches a steady-state level and do not inactivate (PubMed:24495567, PubMed:27516594, PubMed:31490124, PubMed:7925287, PubMed:9400421). The activation kinetics depend on the prepulse potential and external divalent cation concentration. With negative prepulses, the current activation is delayed and slowed down several fold, whereas more positive prepulses speed up activation. The time course of activation is biphasic with a fast and a slowly activating current component. Activates at more positive membrane potentials and exhibit a steeper activation curve (By similarity). Channel properties are modulated by subunit assembly. Mediates IK(NI) current in myoblasts. Involved in the regulation of cell proliferation and differentiation, in particular adipogenic and osteogenic differentiation in bone marrow-derived mesenchymal stem cells (MSCs) (By similarity).
