    • Function

      Phosphorylates ZNF622 and may contribute to its redirection to the nucleus. May be involved in the inhibition of spliceosome assembly during mitosis.
    • Tissue specificity

      Expressed in placenta, kidney, thymus, testis, ovary and intestine.
    • Sequence similarities

      Belongs to the protein kinase superfamily. CAMK Ser/Thr protein kinase family. SNF1 subfamily.
      Contains 1 KA1 (kinase-associated) domain.
      Contains 1 protein kinase domain.
    • Post-translational

      Autophosphorylated. Thr-478 phosphorylation during mitosis promotes interaction with PPP1R8.

    • Lane 1: Wild-type HAP1 cell lysate (20 µg)
      Lane 2: MELK knockout HAP1 cell lysate (20 µg)
      Lane 3: HeLa cell lysate (20 µg)
      Lane 4: HCT116 cell lysate (20 µg)

      Lanes 1 - 4: Merged signal (red and green). Green - ab108529 observed at 75 kDa. Red - loading control, ab8226, observed at 42 kDa.

      ab108529 was shown to recognize MELK when MELK knockout samples were used, along with additional cross-reactive bands. Wild-type and MELK knockout samples were subjected to SDS-PAGE. ab108529 and ab8226 (loading control to beta Actin) were both diluted 1/1000 and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1/10 000 dilution for 1 h at room temperature before imaging.
