Recombinant Mouse Wnk4 Protein, Myc/DDK-tagged

• Cat.No.: Wnk4-7004M
• Product Overview: Purified recombinant protein of Mouse WNK lysine deficient protein kinase 4 (Wnk4), with C-terminal MYC/DDK tag, expressed in HEK293T cells.

Specification

• Species: Mouse
• Source: HEK293
• Tag: DDK&Myc
• Description: 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. Acts as a scaffold to inhibit SLC4A4 as well as CFTR activities and surface expression, recruits STK39 which mediates the inhibition.
