Predicted to enable chloride channel inhibitor activity; potassium channel inhibitor activity; and protein serine/threonine kinase activity. Involved in ion transport. Acts upstream of or within chloride transport; negative regulation of pancreatic juice secretion; and protein localization. Located in bicellular tight junction and cytoplasm. Is expressed in several structures, including alimentary system; metanephros; metatarsal bone; sensory organ; and turbinate bone primordium. Used to study Gitelman syndrome and pseudohypoaldosteronism. Human ortholog(s) of this gene implicated in hypertension and pseudohypoaldosteronism. Orthologous to human WNK4 (WNK lysine deficient protein kinase 4). [provided by Alliance of Genome Resources, Apr 2022]
