Target

  • Function

    Involved in both the initiation and regulation of meiosis, mitosis, and postmitotic functions in differentiated cells by phosphorylating a number of transcription factors such as ELK1. Phosphorylates EIF4EBP1; required for initiation of translation. Phosphorylates microtubule-associated protein 2 (MAP2). Phosphorylates SPZ1 (By similarity). Phosphorylates heat shock factor protein 4 (HSF4) and ARHGEF2.
    Acts as a transcriptional repressor. Binds to a [GC]AAA[GC] consensus sequence. Repress the expression of interferon gamma-induced genes. Seems to bind to the promoter of CCL5, DMP1, IFIH1, IFITM1, IRF7, IRF9, LAMP3, OAS1, OAS2, OAS3 and STAT1. Transcriptional activity is independent of kinase activity.
  • 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
    modifications

    Dually phosphorylated on Thr-185 and Tyr-187, which activates the enzyme. Dephosphorylated by PTPRJ at Tyr-187.
  • Cellular localization

    Nucleus.
  • Target information above from: UniProt accession P28482 The UniProt Consortium
    The Universal Protein Resource (UniProt) in 2010

    Immunofluorescent analysis of ERK1 + ERK2 Antibody was done on 70% confluent log phase U87-MG cells. The cells were fixed with 4% paraformaldehyde for 15 minutes, permeabilized with 0.25% Triton™ X-100 for 10 minutes, and blocked with 5% BSA for 1 hour at room temperature. The cells were labeled with ab17942 at 1:250 dilution in 1% BSA and incubated for 3 hours at room temperature and then labeled with Alexa Fluor 488 Goat Anti-Rabbit IgG Secondary Antibody at a dilution of 1:400 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI. F-actin (Panel c: red) was stained with Alexa Fluor 594 Phalloidin. Panel d is a merged image showing cytoplasmic and nuclear localization. Panel e is a no primary antibody control. The images were captured at 40X magnification.

To expose target proteins, antigen retrieval was performed using 10mM sodium citrate (pH 6.0), microwaved for 8-15 min. Following antigen retrieval, tissues were blocked in 3% H2O2-methanol for 15 min at room temperature, washed with ddH2O and PBS, and then probed with ab17942 diluted in 3% BSA-PBS at a dilution of 1:20 overnight at 4°C in a humidified chamber. Tissues were washed extensively in PBST and detection was performed using an HRP-conjugated secondary antibody followed by colorimetric detection using a DAB kit. Tissues were counterstained with hematoxylin and dehydrated with ethanol and xylene to prep for mounting.

    Western Blot for ab17942.

    Extracts prepared from PC12 cells not stimulated (-), or stimulated with NGF (+) were resolved by SDS-PAGE on a 10% polyacrylamide gel and transferred to nitrocellulose. Membranes were blocked with a 5% BSA-TBST buffer overnight at 4C, then were incubated with ERK1&2 pan antibody for two hours at room temperature in a 3% BSA-TBST buffer. After washing, membranes were incubated
    with goat anti-rabbit IgG alkaline phosphatase.

    These data show that ab17942 ERK1&2 antibody allows the total amount of ERK1&2 to be measured.

    The tissue was harvested seven days post surgery, sonicated with RIPA buffer and the protein estimate made by Lowry. A 10% SDS-PAGE gel was run for 1.5 hr at 100V and transfered to PVDF membrane for 1.5 hr at 274 mA. The blot was blocked with 5% BSA for 1 hour at 23°C. The primary antibody was incubated with the blot for 18 hours at 4°C.

Question

Hola buenos días,
me pongo en contacto con ustedes para comentarles una duda sobre el anticuerpoanti-ERK1+ERK2 ANTIBODY (ab17942) de abcam. A diferencia de otros anticuerpos no especifica ni en la hoja correspondiente ni en el tubito, la concentración a la que está. Solo indica el volumen50 µl ( a pesar de que en la hoja de especificaciones indica este volumen como concentración). Muchas gracias por su atención. Un saludo,

Answer

Gracias por contactarnos.

La concentración de este anticuerpo es dependiente del lote. He conseguido localizar el único pedido que tenemos de la Univ. de XXXXX de este producto para comprobar el lote enviado, que si no me equivoco es XXXXXX


La concentración del mismo es 0.5 mg/mL.

Espero haberte ayudado. En caso contrario, no dudes en contactarnos de nuevo.

Question

Hello, I want an antibody for confocal that is specific for total ERK1 & 2. Is ab17942 the correct one? I also want an antibody specific for phosphorylated ERK1/2 and believe ab50011 is the correct one. The antibody for total ERK should not identify phosphoERK. Could you tell me if these are the correct antibodies.

Answer

For the detection of total ERK1+2 we recommend ab17942, a Rabbit polyclonal directed against amino acids 317-339 of Human ERK1+ERK2. This region is not subject to phosphorylation. ab17942 is covered by our Abpromise guarantee to work in ICC/IF, IHC-Fr, IHC-P, IP, WB and Human, Mouse, Rat, Cow, Dog. For the detection of the phosphorylated ERK1+2 we recommend ab50011, a Mouse monoclonal specific for the active, dually-phosphorylated form of MAP kinase (ERK-1 and ERK-2, 44 kDa and 42 kDa, respectively). It does not recognise the non-phosphorylated or the monophosphorylated forms of the MAP kinase molecule or the diphosphorylated forms of JUN kinase and p38 MAP kinase. The epitope recognized by ab50011 is located in the region of phosphorylated threonine and tyrosine residues within the regulatory site of active MAP kinase (Thr185 and Tyr187 in ERK-2). ab50011 is guaranteed to work in ELISA, ICC/IF, IHC-P, IP, WB and Human, Mouse, Rat, Cow, Drosophila, yeast. I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
