Background
p53 (TP53) (Tumor Protein P53), also known as Phosphoprotein P53, Transformation-Related Protein 53 or Antigen NY-CO-13, is a tumor suppressor protein containing transcriptional activation, DNA binding, and oligomerization domains. It involves in cell cycle regulation as a trans-activator that acts to negatively regulate cell division by controlling a set of genes required for this process. p53 induces the transcription of long intergenic non-coding RNA p21 (lincRNA-p21) and lincRNA-Mkln1, thus participating in TP53-dependent transcriptional repression leading to apoptosis and seem to have to effect on cell-cycle regulation. It is required for apoptosis induction, which seems to be mediated either by stimulation of BAX and FAS antigen expression, or by repression of Bcl-2 expression. In cooperation with mitochondrial PPIF, p53 also is involved in activating oxidative stress-induced necrosis, which is largely independent of transcription.
Application Notes
Recombinant p53 (TP53) protein is suitable for use in the study of protein-protein interaction, in vitro transcription assay, binding assay.

HTRF assay for p53 (TP53) activity
1 µM oligo ds DNA (sequence: 5’-CCGGACATGCCCGGGCATGT-3’) was incubated with p53 (TP53) for 1 hour, then 10 µl FLAG antibody and SA-XL665 mixture (each 1:100 dilution in binding buffer) was added to each reaction system and incubated for 30 min. All the operations and reactions were performed at room temperature. HTRF assay was used for detection.
