This antibody reacts with only mutant p53 protein under non-denaturing conditions (Immunoprecipitation) but reacts with both mutant and wild p53 under denaturing conditions (Western blot). It reacts with an epitope at aa 212-217.
Staining of formalin-fixed, paraffin-embedded tissues requires boiling tissues in 1mM EDTA, pH 8.0, for 10-20 min followed by cooling at room temperature for 20 min.
Recommended positive controls include MDAD-231 cells, SK-BR-3 cells, colon carcinoma, or squamous cell carcinoma.
Background/Target Information
Acts as a tumor suppressor in many tumor types; induces growth arrest or apoptosis depending on the physiological circumstances and cell type. Involved 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. One of the activated genes is an inhibitor of cyclin-dependent kinases. Apoptosis induction 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 is involved in activating oxidative stress-induced necrosis; the function is largely independent of transcription. Induces the transcription of long intergenic non-coding RNA p21 (lincRNA-p21) and lincRNA- Mkln1. LincRNA-p21 participates in TP53-dependent transcriptional repression leading to apoptosis and seem to have to effect on cell-cycle regulation. Implicated in Notch signaling cross-over. Prevents CDK7 kinase activity when associated to CAK complex in response to DNA damage, thus stopping cell cycle progression. Isoform 2 enhances the transactivation activity of isoform 1 from some but not all TP53-inducible promoters. Isoform 4 suppresses transactivation activity and impairs growth suppression mediated by isoform 1. Isoform 7 inhibits isoform 1-mediated apoptosis.
