Potassium channel, subfamily U, member 1,also known asKCNU1,is ageneencoding theK_Ca5.1protein.^[4]

Although this channel is structurally related to thecalcium-activated potassium channels,it cannot be classified as such since it is activated by highintracellular pHand relatively insensitive to changes in calcium concentrations.^[5]^[6]^[7]
