Gene: Scnn1a (sodium channel epithelial 1 alpha subunit) Rattus norvegicus
Symbol: Scnn1a
Name: sodium channel epithelial 1 alpha subunit
Description: Exhibits WW domain binding activity; actin binding activity; and ligand-gated sodium channel activity. Predicted to contribute to sodium channel activity. Involved in regulation of body fluid levels and sodium ion transport. Localizes to the apical plasma membrane; cytoplasm; and sperm principal piece. Used to study nephrotic syndrome. Human ortholog(s) of this gene implicated in Liddle syndrome; autosomal recessive pseudohypoaldosteronism type 1; bronchiectasis; and pseudohypoaldosteronism. Orthologous to human SCNN1A (sodium channel epithelial 1 alpha subunit); PARTICIPATES IN amiloride pharmacodynamics pathway; bendroflumethiazide pharmacodynamics pathway; bumetanide pharmacodynamics pathway; INTERACTS WITH 2,4,6-trinitrotoluene; 2,4-dinitrotoluene; 3'-amino-3'-deoxy-N(6),N(6)-dimethyladenosine.
Type: protein-coding
