Protein attributes

Sequence length	505 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

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.
Subunit structure	Homotetramer or heterotetramer By similarity.
Subcellular location	Cell membrane; Multi-pass membrane protein.
Tissue specificity	Detected in small intestine, duodenum and jejunum. Detected at very low levels in testis and rectum.
Sequence similarities	Belongs to the amiloride-sensitive sodium channel family.
