Disease

S12A3_HUMAN Gitelman syndrome. The disease is caused by variants affecting the gene represented in this entry.

Function

S12A3_HUMAN Electroneutral sodium and chloride ion cotransporter. In kidney distal convoluted tubules, key mediator of sodium and chloride reabsorption (PubMed:21613606, PubMed:22009145). Receptor for the pro-inflammatory cytokine IL18. Contributes to IL18-induced cytokine production, including IFNG, IL6, IL18 and CCL2. May act either independently of IL18R1, or in a complex with IL18R1 (By similarity).[UniProtKB:P59158]^[1] ^[2] S12A2_DANRE Cation-chloride cotransporter which mediates the electroneutral transport of chloride, potassium and/or sodium ions across the membrane (PubMed:31367042). Plays a vital role in the regulation of ionic balance and cell volume (PubMed:31367042). Important for maintenance of endolymph volume in the otic vesicle, probably by regulating ion homeostasis (PubMed:19633174). Also plays a role in normal development of the swim bladder (PubMed:19633174).^[3] ^[4]
