Overview

  • Product name

    Human SMAD2 knockout HeLa cell lysate
    See all Smad2 kits
  • Product overview


    Knockout cell lysate achieved by CRISPR/Cas9.

  • Parental Cell Line

    HeLa
  • Organism

    Human
  • Mutation description

    Knockout achieved by using CRISPR/Cas9, 1 bp deletion in exon2 and 1 bp insertion in exon2.
  • Passage number

    <20
  • Knockout validation

    Sanger Sequencing, Western Blot (WB)
  • Reconstitution notes

    To use as WB control, resuspend the lyophilizate in 50 µL of LDS* Sample Buffer to have a final concentration of 2 mg/ml. For reducing conditions, we recommend a final concentration of 0.1 M DTT.

    *Usage of SDS sample buffer is not recommended with these lyophilized lysates.

  • Notes

    Lysate preparation: Our lysates are made using RIPA buffer to which we add a protease inhibitor cocktail and phosphatase inhibitor cocktail (ratio: 300:100:10). This means that the protein of interest is denatured. If you require a native form of the protein please use the live cell version - found here. Please refer to our lysis protocol for further details on how our lysates are prepared.

    User storage instructions: Lyophilizate may be stored at 4°C. After reconstitution, store at -20°C for short-term storage or -80°C for long-term storage.

    Access thousands of knockout cell lysates, generated from commonly used cancer cell lines.
    See here for more information on knockout cell lysates.

Target

  • Function

    Receptor-regulated SMAD (R-SMAD) that is an intracellular signal transducer and transcriptional modulator activated by TGF-beta (transforming growth factor) and activin type 1 receptor kinases. Binds the TRE element in the promoter region of many genes that are regulated by TGF-beta and, on formation of the SMAD2/SMAD4 complex, activates transcription. May act as a tumor suppressor in colorectal carcinoma.
  • Tissue specificity

    Expressed at high levels in skeletal muscle, heart and placenta.
  • Sequence similarities

    Belongs to the dwarfin/SMAD family.
    Contains 1 MH1 (MAD homology 1) domain.
    Contains 1 MH2 (MAD homology 2) domain.
  • Post-translational
    modifications

    Phosphorylated on one or several of Thr-220, Ser-245, Ser-250, and Ser-255. In response to TGF-beta, phosphorylated on Ser-465/467 by TGF-beta and activin type 1 receptor kinases. Able to interact with SMURF2 when phosphorylated on Ser-465/467, recruiting other proteins, such as SNON, for degradation. In response to decorin, the naturally occurring inhibitor of TGF-beta signaling, phosphorylated on Ser-240 by CaMK2. Phosphorylated by MAPK3 upon EGF stimulation; which increases transcriptional activity and stability, and is blocked by calmodulin.
    In response to TGF-beta, ubiquitinated by NEDD4L; which promotes its degradation.
    Acetylated on Lys-19 by coactivators in response to TGF-beta signaling, which increases transcriptional activity. Isoform short: Acetylation increases DNA binding activity in vitro and enhances its association with target promoters in vivo. Acetylation in the nucleus by EP300 is enhanced by TGF-beta.
  • Cellular localization

    Cytoplasm. Nucleus. Cytoplasmic and nuclear in the absence of TGF-beta. On TGF-beta stimulation, migrates to the nucleus when complexed with SMAD4. On dephosphorylation by phosphatase PPM1A, released from the SMAD2/SMAD4 complex, and exported out of the nucleus by interaction with RANBP1.
