CC -!- FUNCTION: Outward rectifying potassium channel. Produces rapidly
CC activating and non-inactivating outward rectifier K(+) currents.
CC Activated by arachidonic acid and other naturally occurring unsaturated
CC free fatty acids.
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000305}; Multi-pass membrane
CC protein {ECO:0000305}.
CC -!- TISSUE SPECIFICITY: Expressed mainly in the cerebellum, spleen, and
CC testis.
CC -!- SIMILARITY: Belongs to the two pore domain potassium channel (TC
CC 1.A.1.8) family. {ECO:0000305}.
