Wnk3 Gene Summary [Rat]
Predicted to enable molecular condensate scaffold activity; potassium channel inhibitor activity; and protein serine/threonine kinase activity. Predicted to be involved in several processes, including negative regulation of pancreatic juice secretion; regulation of metal ion transport; and regulation of protein localization to plasma membrane. Predicted to act upstream of or within maintenance of blood-brain barrier. Predicted to be located in adherens junction and bicellular tight junction. Predicted to be active in cytoplasm. Human ortholog(s) of this gene implicated in Prieto syndrome. Orthologous to human WNK3 (WNK lysine deficient protein kinase 3). [provided by Alliance of Genome Resources, Apr 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Wnk3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
