Status

Functioni

Sodium permeable non-voltage-sensitive ion channel inhibited by the diuretic amiloride. Mediates the electrodiffusion of the luminal sodium (and water, which follows osmotically) through the apical membrane of epithelial cells. Plays an essential role in electrolyte and blood pressure homeostasis, but also in airway surface liquid homeostasis, which is important for proper clearance of mucus. Controls the reabsorption of sodium in kidney, colon, lung and sweat glands. Also plays a role in taste perception.1 Publication1 Publication

Involvement in diseasei

Pseudohypoaldosteronism 1, autosomal recessive (PHA1B)1 Publication

The disease is caused by mutations affecting the gene represented in this entry. The degree of channel function impairment differentially affects the renin-aldosterone system and urinary Na/K ratios, resulting in distinct genotype-phenotype relationships in PHA1 patients. Loss-of-function mutations are associated with a severe clinical course and age-dependent hyperactivation of the renin-aldosterone system. This feature is not observed in patients with missense mutations that reduce but do not eliminate channel function. Markedly reduced channel activity results in impaired linear growth and delayed puberty (PubMed:18634878).

Disease descriptionA rare salt wasting disease resulting from target organ unresponsiveness to mineralocorticoids. PHA1B is a severe form involving multiple organ systems, and characterized by an often fulminant presentation in the neonatal period with dehydration, hyponatremia, hyperkalemia, metabolic acidosis, failure to thrive and weight loss.

The disease is caused by mutations affecting the gene represented in this entry.

Disease descriptionA debilitating respiratory disease characterized by chronic, abnormal dilatation of the bronchi and other cystic fibrosis-like symptoms in the absence of known causes of bronchiectasis (cystic fibrosis, autoimmune diseases, ciliary dyskinesia, common variable immunodeficiency, foreign body obstruction). Clinical features include sub-normal lung function, sinopulmonary infections, chronic productive cough, excessive sputum production, and elevated sweat chloride in some cases.

Subunit structurei

Heterotrimer containing an alpha/SCNN1A, a beta/SCNN1B and a gamma/SCNN1G subunit. An additional delta/SCNN1D subunit exists only in some organisms and can replace the alpha/SCNN1A subunit to form an alternative channel with specific properties (PubMed:7499195, PubMed:16423824). Interacts with NEDD4 (via WW domains) (PubMed:11244092, PubMed:12167593). Interacts with NEDD4L (via WW domains) (PubMed:11244092). Interacts with WWP1 (via WW domains) (PubMed:9169421). Interacts with WWP2 (via WW domains) (PubMed:9169421, PubMed:12167593). Interacts with the full length immature form of PCSK9 (pro-PCSK9) (PubMed:22493497). Interacts (N-glycosylated) with BPIFA1; the interaction is direct and inhibits the proteolytic processing of SCNN1A and SCNN1G and the activation of ENaC (PubMed:24124190, PubMed:24043776).8 Publications
