Scnn1a Gene Summary [Rat]

Enables WW domain binding activity; actin binding activity; and ligand-gated sodium channel activity. Contributes to sodium ion transmembrane transporter activity. Involved in intracellular sodium ion homeostasis; regulation of body fluid levels; and sodium ion import across plasma membrane. Located in several cellular components, including acrosomal vesicle; apical plasma membrane; and sperm principal piece. Used to study nephrotic syndrome. Human ortholog(s) of this gene implicated in Liddle syndrome; bronchiectasis 2; and pseudohypoaldosteronism. Orthologous to human SCNN1A (sodium channel epithelial 1 subunit alpha).

Protein Domains

A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Scnn1a often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
