Summaries for SCNN1B Gene

Entrez Gene Summary for SCNN1B Gene

  • Nonvoltage-gated, amiloride-sensitive, sodium channels control fluid and electrolyte transport across epithelia in many organs. These channels are heteromeric complexes consisting of 3 subunits: alpha, beta, and gamma. This gene encodes the beta subunit, and mutations in this gene have been associated with pseudohypoaldosteronism type 1 (PHA1), and Liddle syndrome. [provided by RefSeq, Apr 2009]

GeneCards Summary for SCNN1B Gene

SCNN1B (Sodium Channel, Non Voltage Gated 1 Beta Subunit) is a Protein Coding gene. Diseases associated with SCNN1B include liddle syndrome and bronchiectasis with or without elevated sweat chloride 1. Among its related pathways are Activation of cAMP-Dependent PKA and Activation of cAMP-Dependent PKA. GO annotations related to this gene include WW domain binding and ligand-gated sodium channel activity. An important paralog of this gene is SCNN1G.

UniProtKB/Swiss-Prot for SCNN1B Gene

  • 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.

    • Heterotrimer containing one alpha, one beta and one gamma subunit (Probable). A delta subunit also exists in some organisms and can form alternative channels with different 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 (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).

UniProtKB/Swiss-Prot

SCNNB_HUMAN
  • Pseudohypoaldosteronism 1, autosomal recessive (PHA1B) [MIM:264350]: A 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. {ECO:0000269 PubMed:8589714}. Note=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). {ECO:0000269 PubMed:18634878}.
  • Liddle syndrome (LIDDS) [MIM:177200]: Autosomal dominant disorder characterized by pseudoaldosteronism and hypertension associated with hypokalemic alkalosis. The disease is caused by constitutive activation of the renal epithelial sodium channel. {ECO:0000269 PubMed:15483078, ECO:0000269 PubMed:7550319, ECO:0000269 PubMed:8524790, ECO:0000269 PubMed:8601645, ECO:0000269 PubMed:9626162, ECO:0000269 PubMed:9794716}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Bronchiectasis with or without elevated sweat chloride 1 (BESC1) [MIM:211400]: A 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. {ECO:0000269 PubMed:16207733, ECO:0000269 PubMed:18507830, ECO:0000269 PubMed:19017867}. Note=The disease is caused by mutations affecting the gene represented in this entry.
