    • 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 and SGK1. Controls sodium and chloride ion transport by inhibiting the activity of WNK4, by either phosphorylating the kinase or via an interaction between WNK4 and the autoinhibitory domain of WNK1. WNK4 regulates the activity of the thiazide-sensitive Na-Cl cotransporter, SLC12A3, by phosphorylation. WNK1 may also play a role in actin cytoskeletal reorganization. Phosphorylates NEDD4L. Acts as a scaffold to inhibit SLC4A4, SLC26A6 as well as CFTR activities and surface expression, recruits STK39 which mediates the inhibition.
    • Tissue specificity

      Widely expressed, with highest levels observed in the testis, heart, kidney and skeletal muscle. Isoform 3 is kidney-specific and specifically expressed in the distal convoluted tubule (DCT) and connecting tubule (CNT) of the nephron.
    • Involvement in disease

      Pseudohypoaldosteronism 2C
      Neuropathy, hereditary sensory and autonomic, 2A
    • Sequence similarities

      Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. WNK subfamily.
      Contains 1 protein kinase domain.
    • Post-translational

      Ubiquitinated in vitro by the BCR(KLHL3) complex and in vivo by a BCR(KLHL2) complex, leading to proteasomal degradation.

    • Lane 1: Wild type HAP1 whole cell lysate (40 µg)
      Lane 2: WNK1 knockout HAP1 whole cell lysate (40 µg)

      Lanes 1 - 2: Merged signal (red and green). Green - ab174854 observed at 300 kDa. Red - loading control, ab18058, observed at 130 kDa.

      ab174854 was shown to recognize WNK1 when WNK1 knockout samples were used, along with additional cross-reactive bands. Wild-type and WNK1 knockout samples were subjected to SDS-PAGE. Ab174854 and ab18058 (Mouse anti Vinculin loading control) were incubated overnight at 4°C at 1000 dilution and 1/10000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.
