  • Application notes
    Is unsuitable for IHC-P or IP.
  • Target

    • Function

      Responds to activation by environmental stress and pro-inflammatory cytokines by phosphorylating a number of transcription factors, primarily components of AP-1 such as c-Jun and ATF2 and thus regulates AP-1 transcriptional activity. Required for stress-induced neuronal apoptosis and the pathogenesis of glutamate excitotoxicity.
    • Tissue specificity

      Specific to a subset of neurons in the nervous system. Present in the hippocampus and areas, cerebellum, striatum, brain stem, and weakly in the spinal cord. Very weak expression in testis and kidney.
    • Involvement in disease

      Defects in MAPK10 are a cause of epileptic encephalopathy Lennox-Gastaut type (EELG) [MIM:606369]. Epileptic encephalopathies of the Lennox-Gastaut group are childhood epileptic disorders characterized by severe psychomotor delay and seizures. Note=A chromosomal aberration involving MAPK10 has been found in a single patient. Translocation t(Y;4)(q11.2;q21) which causes MAPK10 truncation.
    • 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-221 and Tyr-223, which activates the enzyme. Weakly autophosphorylated on threonine and tyrosine residues in vitro.

    • Overlay histogram showing SHSY-5Y cells stained with ab126591 (red line). The cells were fixed with 4% paraformaldehyde (10 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab126591, 1/10000 dilution) for 30 min at 22°C. The secondary antibody used was Alexa Fluor® 488 goat anti-rabbit IgG (H&L) (ab150077) at 1/2000 dilution for 30 min at 22°C. Isotype control antibody (black line) was rabbit IgG (monoclonal) (0.1μg/1x106 cells) used under the same conditions. Unlabelled sample (blue line) was also used as a control. Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter. This antibody gave a positive signal in SHSY-5Y cells fixed with 80% methanol (5 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.

    Customer reviews and Q&As


    The immunogen of this antibody corresponds to a region within amino acids 400-450 of the protein. This has 100% homology with Isoform Alpha-2 (53 kDa) and Isoform 3 (48 kDa) but no homology with Isoform Alpha-1 and Isoform 4. Please see the uniprot entry for this protein for more information on the isoforms: http://www.uniprot.org/uniprot/P53779

    This antibody can therefore detect bands at 53 kDa and 48 kDa which would explain the results you have obtained.
