描述兔多克隆抗体to ERK5 (phospho T218 + Y220)
特异性Some 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.
经测试应用适用于: WBmore details
Synthetic phosphopeptide derived from the region of human ERK5 that contains threonine 218 and tyrosine 220.
- HEK293 cells transiently co-transfected with plasmids expressing ERK5 kinase domain (ERK5kin)and constitutively activated MEK5 (MEK5D-D).
Reproducibility is key to advancing scientific discovery and accelerating scientists’ next breakthrough.
Abcam is leading the way with our range of recombinant antibodies, knockout-validated antibodies and knockout cell lines, all of which support improved reproducibility.
We are also planning to innovate the way in which we present recommended applications and species on our product datasheets, so that only applications & species that have been tested in our own labs, our suppliers or by selected trusted collaborators are covered by our Abpromise™ guarantee.
In preparation for this, we have started to update the applications & species that this product is Abpromise guaranteed for.
We are also updating the applications & species that this product has been “predicted to work with,” however this information is not covered by our Abpromise guarantee.
Applications & species from publications and Abreviews that have not been tested in our own labs or in those of our suppliers are not covered by the Abpromise guarantee.
Please check that this product meets your needs before purchasing.

纯度Immunogen affinity purified
纯化说明The antibody has been negatively preadsorbed using a non-phosphopeptide corresponding to the site of phosphorylation to remove antibody that is reactive with non-phosphorylated ERK5. The final product is generated by affinity chromatography using an ERK5-derived peptide that is phosphorylated at threonine 218 and tyrosine 220.
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.
|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.|
功能Plays 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.
组织特异性Expressed in many adult tissues. Abundant in heart, placenta, lung, kidney and skeletal muscle. Not detectable in liver.
序列相似性Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. MAP kinase subfamily.
Contains 1 protein kinase domain.
结构域The 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.
翻译后修饰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.
细胞定位Cytoplasm. Nucleus. Translocates to the nucleus upon activation.

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&
