  • Purity> 95 % SDS-PAGE.

  • FormLiquid
  • Additional notes

    This peptide may be used for neutralization and control experiments with the polyclonal antibody that reacts with this product, FE65 catalog ab5668. Using a solution of peptide of equal volume and concentration to the corresponding antibody will yield a large molar excess of peptide ( 70-fold) for competitive inhibition of antibody-protein binding reactions.

  • FunctionTranscription coregulator that can have both coactivator and corepressor functions. Adapter protein that forms a transcriptionally active complex with the gamma-secretase-derived amyloid precursor protein (APP) intracellular domain. Plays a central role in the response to DNA damage by translocating to the nucleus and inducing apoptosis. May act by specifically recognizing and binding histone H2AX phosphorylated on 'Tyr-142' (H2AXY142ph) at double-strand breaks (DSBs), recruiting other pro-apoptosis factors such as MAPK8/JNK1. Required for histone H4 acetylation at double-strand breaks (DSBs). Its ability to specifically bind modified histones and chromatin modifying enzymes such as KAT5/TIP60, probably explains its trancription activation activity. Function in association with TSHZ3, SET and HDAC factors as a transcriptional repressor, that inhibits the expression of CASP4. Associates with chromatin in a region surrounding the CASP4 transcriptional start site(s).
  • Tissue specificityHighly expressed in brain; strongly reduced in post-mortem elderly subjects with Alzheimer disease.
  • Sequence similaritiesContains 2 PID domains.
    Contains 1 WW domain.
  • Post-translational
    Phosphorylated following nuclear translocation. Phosphorylation at Tyr-546 enhances the transcription activation activity and reduces the affinity with RASD1/DEXRAS1.
  • Cellular localizationCell membrane. Cytoplasm. Nucleus. Cell projection > growth cone. Colocalizes with TSHZ3 in axonal growth cone (By similarity). In normal conditions, it mainly localizes to the cytoplasm, while a small fraction is tethered to the cell membrane via its interaction with APP. Following exposure to DNA damaging agents, it is released from cell membrane and translocates to the nucleus. Nuclear translocation is under the regulation of APP. Colocalizes with TSHZ3 in the nucleus.
