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. Human ortholog(s) of this gene implicated in Liddle syndrome; bronchiectasis 3; and pseudohypoaldosteronism. Orthologous to human SCNN1G (sodium channel epithelial 1 subunit gamma). [provided by Alliance of Genome Resources, Dec 2024]

The SCNN1G defects triggered programmed cell death via inhibiting miR-21 and upregulating PTEN, which then orchestrated the key downstream regulators, including Bcl2, Bax2, and cleaved Caspse-3 in a way that favors cell apoptosis.
Title: A novel SCNN1G mutation in a PHA I infant patient correlates with nephropathy.
The presence of active plasmin in urine in hydronephrosis could cause abnormal proteolytic activation of ENaC-gamma and impaired ability to excrete Na via NCC.
Title: Hydronephrosis is associated with elevated plasmin in urine in pediatric patients and rats and changes in NCC and γ-ENaC abundance in rat kidney.
these findings reveal ENaC as an interactor and potential regulator of Cav3.2 calcium channels expressed in neuronal tissues.
Title: Cav3.2 calcium channel interactions with the epithelial sodium channel ENaC.
Based on the widespread presence of ENaC along the epididymis we suggest that mutations in ENaC subunits may also be associated with male infertility.
Title: Mapping the sites of localization of epithelial sodium channel (ENaC) and CFTR in segments of the mammalian epididymis.
gammaENaC may play an important role in the elevated myogenic response in Posterior Cerebral Arteries.
Title: Involvement of Epithelial Na(+) Channel in the Elevated Myogenic Response in Posterior Cerebral Arteries from Spontaneously Hypertensive Rats.
Decreased in plasma aldosterone, Na(+) and ENaC levels in kidneys under testosterone influence indicated that testosterone-induced increased in mean arterial pressure (MAP) were not due to increased plasma aldosterone and ENaC levels in kidneys, and thus the testosterone effect on MAP likely involve other mechanisms.
Title: Changes in plasma aldosterone and electrolytes levels, kidney epithelial sodium channel (ENaC) and blood pressure in normotensive WKY and hypertensive SHR rats following gonadectomy and chronic testosterone treatment.
Data suggest that dietary factors can regulate cardiac Scnn1g, Nedd4-2, and Sgk1 activity; here, proanthocyanidin dietary supplement PRO80 blocks aldosterone-dependent up-regulation of Scnn1g, Nedd4-2, and Sgk1 content in cardiac dysfunction. (Scnn1g = epithelial sodium channel 1, gamma subunit; Nedd4-2 = ubiquitin-protein ligase Nedd4-2; Sgk1 = serum-glucocorticoid regulated kinase 1)
Title: Proanthocyanidins block aldosterone-dependent up-regulation of cardiac gamma ENaC and Nedd4-2 inactivation via SGK1.
This study demonstrated that the formation of the heminodal Nav channel cluster adjacent to the presynaptic terminal occurs around hearing onset in the second week of postnatal age.

Kidneys respond acutely to hyperkalemic challenges by decreasing the activity of NCC while increasing that of ENaC.

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.
