function:Exhibits outward rectification in a physiological K(+) gradient and mild inward rectification in symmetrical K(+) conditions.,miscellaneous:Inhibited by internal acidification and, to a small degree, by zinc. Not inhibited by quinine, quinidine or barium.,similarity:Belongs to the two pore domain potassium channel (TC 1.A.1.8) family.,subunit:Homodimer .,tissue specificity:Widespread expression, detected in all tissues tested except for skeletal muscle. Strongest expression in placenta, pancreas, heart, colon and spleen, lower levels detected in peripheral blood leukocytes, lung, liver, kidney and thymus. Lowest expression detected in brain.,
