Potassium channel, subfamily U, member 1, also known as KCNU1, is a gene encoding the K_Ca5.1 protein.

Although this channel is structurally related to the calcium-activated potassium channels, it cannot be classified as such since it is activated by high intracellular pH and relatively insensitive to changes in calcium concentrations.
