  • Description
    Rabbit polyclonal to ERK5 (phospho T218 + Y220)
  • SpecificitySome cross-reactivity is observed with endogenous ERK1 and 2 (44 and 42 kDa, respectively) due to the high levels of expression and activation of this protein typically observed with most cell types.
  • Tested applicationsSuitable for: WB, IHC-Frmore details
  • Species reactivity
    Reacts with: Human
    Predicted to work with: Mouse
  • Immunogen

    Synthetic phosphopeptide derived from the region of human ERK5 that contains threonine 218 and tyrosine 220.

  • Positive control
    • HEK293 cells transiently co-transfected with plasmids expressing ERK5 kinase domain (ERK5kin)and constitutively activated MEK5 (MEK5D-D).



Our Abpromise guarantee covers the use of ab5686 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 1/1000. Predicted molecular weight: 88 kDa. Due to the low abundance and low levels of activation of endogenous ERK5, over-expression or immunoprecipitation may be required.
IHC-Fr Use at an assay dependent concentration.


  • FunctionPlays a role in various cellular processes such as proliferation, differentiation and cell survival. The upstream activator of MAPK7 is the MAPK kinase MAP2K5. Upon activation, it translocates to the nucleus and phosphorylates various downstream targets including MEF2C. EGF activates MAPK7 through a Ras-independent and MAP2K5-dependent pathway. May have a role in muscle cell differentiation. May be important for endothelial function and maintenance of blood vessel integrity. MAP2K5 and MAPK7 interact specifically with one another and not with MEK1/ERK1 or MEK2/ERK2 pathways.
  • Tissue specificityExpressed in many adult tissues. Abundant in heart, placenta, lung, kidney and skeletal muscle. Not detectable in liver.
  • Sequence similaritiesBelongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. MAP kinase subfamily.
    Contains 1 protein kinase domain.
  • DomainThe second proline-rich region may interact with actin targeting the kinase to a specific location in the cell.
    The TXY motif contains the threonine and tyrosine residues whose phosphorylation activates the MAP kinases.
  • Post-translational
    Dually phosphorylated on Thr-219 and Tyr-221, which activates the enzyme (By similarity). Autophosphorylated in vitro on threonine and tyrosine residues when the C-terminal part of the kinase, which could have a regulatory role, is absent.
  • Cellular localizationCytoplasm. Nucleus. Translocates to the nucleus upon activation.

  • Predicted band size : 88 kDa

    Peptide Competition: Extracts prepared from HEK293 cells transiently transfected with plasmids expressing ERK5 kinase domain (ERK5kin) and constitutively activated MEK5D-D were resolved by SDS-PAGE on a 10% polyacrylamide gel and transferred to PVDF. Membranes were blocked with a 5% BSA TBST buffer overnight at 4oC, then were incubated with the ab5686 antibody for two hours at room temperature in a 3% BSATBST buffer, following prior incubation with: no peptide (1), the non-phosphopeptide corresponding to the immunogen (2), a generic phosphothreonine-containing peptide (3), a generic phosphotyrosine-containing peptide (4), the phosphopeptide derived from the corresponding region of ERK1&2 (5), or, the phosphopeptide immunogen (6). After washing, membranes were incubated with goat F(ab’ 2 anti-rabbit IgG alkaline phosphatase conjugate and bands were detected using the Tropix WesternStarTM detection method. The data show that while there is some cross-reactivity with ERK1&2, only the phosphopeptide corresponding to ERK5 [pTpY218/220] completely blocks the antibody signal, demonstrating the specificity of the antibody. NOTE: The antibody signal appears at ~50 kDa as this is the molecular weight of the transiently transfected ERK5 kinase domain.
