function:Cation channel that gives rise to very low constitutive currents in the absence of activation. The activated channel exhibits selectivity for sodium, and is inhibited by amiloride.,similarity:Belongs to the amiloride-sensitive sodium channel family.,subunit:Homotetramer or heterotetramer.,tissue specificity:Detected in small intestine, duodenum and jejunum. Detected at very low levels in testis and rectum.,
