  • Target

    • FunctionParticipates in the apoptotic response to DNA damage. Isoforms containing the transactivation domain are pro-apoptotic, isoforms lacking the domain are anti-apoptotic and block the function of p53 and transactivating p73 isoforms. May be a tumor suppressor protein.
    • Tissue specificityExpressed in striatal neurons of patients with Huntington disease (at protein level). Brain, kidney, placenta, colon, heart, liver, spleen, skeletal muscle, prostate, thymus and pancreas. Highly expressed in fetal tissue.
    • Sequence similaritiesBelongs to the p53 family.
      Contains 1 SAM (sterile alpha motif) domain.
    • DomainPossesses an acidic transactivation domain, a central DNA binding domain and a C-terminal oligomerization domain that binds to the ABL tyrosine kinase SH3 domain.
      The WW-binding motif mediates interaction with WWOX.
    • Post-translational
      modifications
      Isoform alpha (but not isoform beta) is sumoylated on Lys-627, which potentiates proteasomal degradation but does not affect transcriptional activity.
      Higher levels of phosphorylation seen in the brain from patients with Huntington disease.
      Ubiquitinated; leading to its degradation by the proteasome.
    • Cellular localizationNucleus. Accumulates in the nucleus in response to DNA damage.

    • Ab39424 staining human normal skin tissue. Staining is localised to nucleus.
      Left panel: with primary antibody at 2 ug/ml. Right panel: isotype control.
      Sections were stained using an automated system DAKO Autostainer Plus , at room temperature. Sections were rehydrated and antigen retrieved with the Dako 3-in-1 antigen retrieval buffers EDTA pH 9.0 in a DAKO PT Link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 minutes. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 minutes and detected with Dako Envision Flex amplification kit for 30 minutes. Colorimetric detection was completed with diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that for manual staining we recommend to optimize the primary antibody concentration and incubation time (overnight incubation), and amplification may be required.
