    Database link: O15350

  • 阳性对照
    • 293T, MCF7 and COS-1 cells.
  • 常规说明Centrifuge tube to remove product from lid. This antibody has ben tested in ChIP at an inducible promotor held on a vector. There was very siginifant enrichment following induction at the locus analysed. This antibody works well in ChIP in this assay.



Our Abpromise guarantee covers the use of ab14430 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

应用 Ab评论 说明
WB 1/2500 - 1/10000. Detects a band of approximately 65 kDa (predicted molecular weight: 70 kDa).
IP Use at 1-4 µg/mg of lysate.
IHC-P Use at an assay dependent concentration. PubMed: 16630058
ChIP Use at an assay dependent concentration. PubMed: 21459846


  • 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.
