ELISA 1/10000.
IHC-P Use at an assay dependent concentration.


  • 功能Participates 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.
  • 组织特异性Expressed 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.
  • 序列相似性Belongs to the p53 family.
    Contains 1 SAM (sterile alpha motif) domain.
  • 结构域Possesses 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.
  • 翻译后修饰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.
  • 细胞定位Nucleus. Accumulates in the nucleus in response to DNA damage.
