  • Concentration information loading...
  • Purity
    Immunogen affinity purified
  • Purification notes
    ab74032 was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific phosphopeptide. The antibody against non-phosphopeptide was removed by chromatography using non-phosphopeptide corresponding to the phosphorylation site.

Our Abpromise guarantee covers the use of ab74032 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB 1/500 - 1/1000. Detects a band of approximately 90 kDa (predicted molecular weight: 83 kDa).
ELISA 1/10000.
IHC-P 1/50 - 1/100.


  • Function
    Phosphorylates microtubule-associated protein 2 (MAP2). May promote entry in the cell cycle.
  • Tissue specificity
    Highest expression in the skeletal muscle, followed by the brain. Also found in heart, placenta, lung, liver, pancreas, kidney and skin fibroblasts.
  • Sequence similarities
    Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. MAP kinase subfamily.
    Contains 1 protein kinase domain.
  • Domain
    The TXY motif contains the threonine and tyrosine residues whose phosphorylation activates the MAP kinases.
  • Post-translational
    Dually phosphorylated on Thr-626 and Tyr-628, which activates the enzyme.
