Summary: Enables WW domain binding activity and ligand-gated sodium channel activity. Contributes to sodium ion transmembrane transporter activity. Involved in several processes, including intracellular sodium ion homeostasis; sodium ion import across plasma membrane; and wound healing, spreading of epidermal cells. Located in apical plasma membrane and cell surface. Used to study nephrotic syndrome. Human ortholog(s) of this gene implicated in Liddle syndrome; bronchiectasis 1; and pseudohypoaldosteronism. Orthologous to human SCNN1B (sodium channel epithelial 1 subunit beta). [provided by Alliance of Genome Resources, Dec 2024]
Expression: Biased expression in Kidney (RPKM 115.1), Lung (RPKM 56.7) and 3 other tissues See more

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
