Summary: Enables WW domain binding activity and ligand-gated sodium channel activity. Contributes to sodium channel activity. Involved in intracellular sodium ion homeostasis and sodium ion import across plasma membrane. Acts upstream of or within several processes, including artery smooth muscle contraction; cellular response to aldosterone; and mucus secretion. Located in external side of plasma membrane. Part of sodium channel complex. Is expressed in several structures, including aorta; endocrine gland; genitourinary system; lung; and stomach. Used to study Liddle syndrome; autosomal recessive pseudohypoaldosteronism type 1; and cystic fibrosis. Human ortholog(s) of this gene implicated in Liddle syndrome; bronchiectasis 1; and pseudohypoaldosteronism. Orthologous to human SCNN1B (sodium channel epithelial 1 subunit beta).

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.

RNA

NR_073548.1 RNA Sequence

Status: VALIDATED

Description

Transcript Variant: This variant (3) uses an alternate splice site in an internal exon, compared to variant 1. This variant is represented as non-coding because the use of the 5'-most expected translational start codon, as used in variant 1, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
