SK channels (Small conductance calcium-activated potassium channels) are a subfamily of Ca2+-activated K+ channels. They are so called because of their small single channel conductance in the order of 10 pS. SK channels are a type of ion channel allowing potassium cations to cross the cell membrane and are activated (opened) by an increase in the concentration of intracellular calcium through N-type calcium channels.
