靶點詳情

  • 功能：
    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.

    1. reduced age-dependent weight gain of WNK1 TG mice seems to be related with the decreased Kir6.2 expression via WNK1- and WNK4-regulated protein stability of Kir6.2. PMID: 29392534
    2. WNK4 protein affected the DNA-binding ability of C/EBPbeta and thereby reduced PPARgamma expression. In the WNK4(-/-) mice, PPARgamma and C/EBPalpha expression were decreased in adipose tissues, and the mice exhibited partial resistance to high-fat diet-induced adiposity. PMID: 28314693
    3. However, phosphorylation of SPAK and NCC at distal convoluted tubules were almost completely absent even in WNK4(-/-)KLHL3(R528H/R528H) mice. In conclusion, increased WNK1 was unable to compensate for WNK4 deficiency and phosphorylate the NCC, indicating that WNK4 is indispensable for the onset of PHAII. PMID: 28743496
    4. ENaC and ROMK channel activity in kidney tubules are inhibited in TgWnk4(pseudoaldosteronism type II) mice. Wnk4(PHAII)-induced inhibition of ENaC and ROMK may contribute to the suppression of K(+) secretion in the tubules. PMID: 28365586
    5. Accordingly, medullary WNK4 protein levels were significantly increased in the kidneys of KLHL2(-/-) mice. KLHL2 is indeed a physiological regulator of WNK4 in vivo; however, its function might be different from that of KLHL3 because KLHL2 mainly localized in medulla. PMID: 28414128
    6. The results indicate that quite modest changes in dietary K intake affect plasma [K] and thiazide-sensitive NaCl cotransporter activity. These effects are mediated largely by WNK4, as this kinase exhibits unique Cl-sensitive properties. PMID: 26422504
    7. the increased NCC expression and activation is present in CMA which is highly associated with the enhanced WNK4-SPAK signal pathway using WNK4-/- and SPAK-/- mice. PMID: 26728390
    8. increased protein expression levels of WNK1 and WNK4 kinases cause PHAII by KLHL3 R528H mutation due to impaired KLHL3-Cullin3-mediated ubiquitination. PMID: 24821705
    9. KLHL3 is phosphorylated at serine 433 in the Kelch domain (a site frequently mutated in hypertension with hyperkalemia) by protein kinase C in cultured cells and that this phosphorylation prevents WNK4 binding and degradation. PMID: 25313067

    16. these results suggest that these PHAII-causing mutations disrupt a Ca(2+)-sensing mechanism around the acidic motif necessary for the regulation of WNK4 kinase activity by Ca(2+) ions. PMID: 22342722
    17. Immunolocalization of WNK4 in mouse kidney. PMID: 21660484
    18. Results clearly establish that PHAII caused by the WNK4 D561A mutation is dependent on the activation of the WNK-OSR1/SPAK-NCC cascade. PMID: 21486947
    19. beta(2)-adrenergic receptor stimulation led to decreased transcription of the gene encoding WNK4, a regulator of sodium reabsorption PMID: 21499270

    27. Nephron segments that express WNK1-S & WNK4 mRNA have major influence on long-term NaCl reabsorption. WNK pathway responds with significant upregulation of WNK1-S & WNK4 with high K+ intake & reduction in WNK1-S on chronic lowering of K+ or Na+ intake. PMID: 16899520
