Summary: Contributes to chloride channel activity. Predicted to be involved in chloride transport. Predicted to act upstream of or within cellular ion homeostasis. Located in basolateral plasma membrane. Is integral component of plasma membrane. Part of protein-containing complex. Is expressed in central nervous system; inner ear; and metanephros. Used to study Bartter disease type 4a. Human ortholog(s) of this gene implicated in Bartter disease; Bartter disease type 4a; and sensorineural hearing loss. Orthologous to human BSND (barttin CLCNK type accessory subunit beta). [provided by Alliance of Genome Resources, Apr 2022]

Mouse genetics reveals Barttin as a genetic modifier of Joubert syndrome.
Title: Mouse genetics reveals Barttin as a genetic modifier of Joubert syndrome.
our study provides in vivo evidence that, in response to a low-potassium diet, ClC-K and barttin play important roles in the activation of the WNK4-SPAK-NCC cascade and blood pressure regulation.
Title: Role of ClC-K and barttin in low potassium-induced sodium chloride cotransporter activation and hypertension in mouse kidney.
induction of SGK1, CLC-K1 and barttin by high osmolarity and change in intracellular volume in distal renal tubular cells in vivo and in vitro
Title: High osmolality induces the kidney-specific chloride channel CLC-K1 by a serum and glucocorticoid-inducible kinase 1 MAPK pathway.
Bsnd(-/-) mice thus demonstrate a novel function of Cl(-) channels in generating the endocochlear potential and reveal the mechanism leading to deafness in human Bartter syndrome IV.

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.
