84-4355-45　p53, phosphorylated (Ser20) 100ul　327236

特徴

• 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.
• Applications:Suitable for use in Western Blot.
• Other applications not tested.
• Recommended Dilution:Western Blot: 1:500-1:1000Optimal dilutions to be determined by the researcher.
