Gene name:
WNK4 (PRKWNK4) ;
Protein name:
Serine/threonine-protein kinase WNK4 ;
Alternative:
Protein kinase with no lysine 4 ;Protein kinase lysine-deficient 4 ;
Organism:
Human (Homo sapiens).
General Annotation
Sub Unit:
Interacts with the C-terminal region of KCNJ1 (By similarity). Interacts with WNK1 and WNK3.
Function:
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 SCNN1A, SCNN1B, SCNN1D, SGK1, TRPV5 and TRPV6. Regulates the activity of the thiazide-sensitive Na-Cl cotransporter, SLC12A3, by phosphorylation which appears to prevent membrane trafficking of SLC12A3. Also inhibits the renal K(+) channel, KCNJ1, via a kinase-independent mechanism by which it induces clearance of the protein from the cell surface by clathrin-dependent endocytosis. WNK4 appears to act as a molecular switch that can vary the balance between NaCl reabsorption and K(+) secretion to maintain integrated homeostasis. Phosphorylates NEDD4L.
Subcellular Location:
Cell junction
tight junction
Present exclusively in intercellular junctions in the distal convoluted tubule and in both the cytoplasm and intercellular junctions in the cortical collecting duct. WNK4 is part of the tight junction complex.
