  • Target

    • Function
      Its physiological substrate seems to be the small heat shock protein (HSP27/HSP25). In vitro can phosphorylate glycogen synthase at 'Ser-7' and tyrosine hydroxylase (on 'Ser-19' and 'Ser-40'). This kinase phosphorylates Ser in the peptide sequence, Hyd-X-R-X(2)-S, where Hyd is a large hydrophobic residue (By similarity). Mediates both ERK and p38 MAPK/MAPK14 dependent neutrophil responses. Participates in TNF alpha-stimulated exocytosis of secretory vesicles in neutrophils. Plays a role in phagocytosis-induced respiratory burst activity.
    • Tissue specificity
      Expressed in all tissues examined.
    • Sequence similarities
      Belongs to the protein kinase superfamily. CAMK Ser/Thr protein kinase family.
      Contains 1 protein kinase domain.
    • Post-translational
      Phosphorylated and activated by MAP kinase.

    • Lane 1: Wild-type HAP1 cell lysate (20 µg)
      Lane 2: MAPKAP Kinase 2knockout HAP1 cell lysate (20 µg)
      Lane 3: HeLa cell lysate (20 µg)
      Lane 4: A431 cell lysate (20 µg)
      Lanes 1 - 4: Merged signal (red and green). Green - ab32567 observed at 48 kDa. Red - loading control, ab8245, observed at 37 kDa.

      ab32567 was shown to specifically react with MAPKAP Kinase 2 when MAPKAP Kinase 2 knockout samples were used. Wild-type and MAPKAP Kinase 2 knockout samples were subjected to SDS-PAGE. ab32567 and ab8245 (loading control to ProteinX2) were diluted to 1/500 and 1/1000 respectively 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 1/10000 dilution for 1 hour at room temperature before imaging.

      All lanes : IRDye® 680 LICOR goat anti-rabbit.

      Performed under reducing conditions.

      Predicted band size: 46 kDa
      Observed band size: 48 kDa (why is the actual band size different from the predicted?)
      Additional bands at: 55 kDa (possible cross reactivity)

      Exposure time: 1 minute

      ab32567 recognise total MK2 (lane 3,4). A control for specificity is shown as UV treated HeLa + p38 inhibitor (lane 2,4). While the intensity of pT334 band is greatly reduced (lane 2), total MK2 remains unaltered (lane 4).
