Protein

Serine/threonine-protein kinase WNK3

Gene

Wnk3

Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at transcript leveli

Functioni

Serine/threonine kinase which plays an important role in the regulation of electrolyte homeostasis, cell signaling, survival and proliferation. Acts as an activator and inhibitor of sodium-coupled chloride cotransporters and potassium-coupled chloride cotransporters respectively. Activates SLC12A1, SLC12A2, SLC12A3, SCNN1A, SCNN1B, SCNN1D and SGK1. Inhibits SLC12A4, SLC12A5, SLC12A6 and SLC12A7. Phosphorylates WNK4. Increases Ca2+ influx mediated by TRPV5 and TRPV6 by enhancing their membrane expression level via a kinase-dependent pathway. Inhibits KCNJ1 by decreasing its expression at the cell membrane in a non-catalytic manner.1 Publication

Catalytic activityi

ATP + a protein = ADP + a phosphoprotein.

Cofactori

Magnesium.By similarity

Enzyme regulationi

Activation requires autophosphorylation of Ser-307. Phosphorylation of Ser-303 also promotes increased activity. Kinase activity is inhibited by WNK4 (By similarity).By similarity
