Application Abreviews Notes
WB 1/500 - 1/1000. Predicted molecular weight: 93 kDa.


  • Function

    Activates the JUN N-terminal pathway. Required for serum-stimulated cell proliferation and for mitogen and cytokine activation of MAPK14 (p38), MAPK3 (ERK) and MAPK8 (JNK1). Plays a role in mitogen-stimulated phosphorylation and activation of BRAF, but does not phosphorylate BRAF directly. Influences microtubule organization during the cell cycle.
  • Tissue specificity

    Expressed in a wide variety of normal and neoplastic tissues including fetal lung, liver, heart and kidney, and adult lung, liver, heart, kidney, placenta, skeletal muscle, pancreas and brain.
  • Sequence similarities

    Belongs to the protein kinase superfamily. STE Ser/Thr protein kinase family. MAP kinase kinase kinase subfamily.
    Contains 1 protein kinase domain.
    Contains 1 SH3 domain.
  • Post-translational

    Autophosphorylation on serine and threonine residues within the activation loop plays a role in enzyme activation. Thr-277 is likely to be the main autophosphorylation site. Phosphorylation of Ser-555 and Ser-556 is induced by CDC42.
  • Cellular localization

    Cytoplasm > cytoskeleton > centrosome. Location is cell cycle dependent.
