Western blot - HRP Anti-p53 antibody [DO-1] (AB204452)

This blot was produced using a 4-12% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 2% Bovine Serum Albumin before being incubated with ab204452 overnight at 4°C. Antibody binding was visualised using ECL development solution ab133406.

Western blot - HRP Anti-p53 antibody [DO-1] (AB204452)

ab204452 was shown to specifically react with p53 in wild-type HAP1 cells as signal was lost in TP53 (p53) knockout cells. Wild-type and TP53 (p53) knockout samples were subjected to SDS-PAGE. ab204452 and ab184095 (Mouse monoclonal [mAbcam 9484] to GAPDH - Loading Control (Alexa Fluor® 680) loading control) were incubated overnight at 4°C at 1/5000 dilution and 1/1000 dilution respectively. The loading control was imaged using the Licor Odyssey CLx prior to blots being developed with ECL technique.

Immunogen

The exact immunogen used to generate this antibody is proprietary information.

Epitope

ab204452 recognizes an epitope within aa 20-25 at the N-terminus of Human p53.

Specificity

This antibody clone recognises both wild-type and mutant forms of p53 in human samples. It is not designed to recognise any specific p53 mutation.

We have confirmed this experimentally and have been able to detect p53 in different cell lines using various applications and treatments.

Important note: p53 expression levels vary greatly between cell lines. It has been reported that p53 mutations render the protein more stable, hence mutated cell lines often express higher levels of the p53 protein compared to wild-type cell lines. For low expressing wild type cell lines, p53 expression can be increased with cell treatments such as camptothecin or irinotecan.

Supplementary information

This supplementary information is collated from multiple sources and compiled automatically.

The protein p53 also known as TP53 or tumor protein p53 has a molecular weight of approximately 53 kDa. It acts as a transcription factor and plays a major role in cell cycle regulation apoptosis and maintaining genomic stability. This protein mainly expresses in the nucleus of cells and acts as a critical regulator of cellular responses to stress signals including DNA damage. Scientists commonly use p53 antibodies in various assays like western blot and p53 immunofluorescence to detect and study its expression and functional status in cells.
Biological function summary

P53 functions to control cell division and apoptosis serving as a guardian of the genome by preventing mutation accumulation. It does not form part of a larger complex under normal conditions but interacts with various other molecules to execute its functions. p53 can activate or suppress the transcription of numerous genes involved in cell cycle arrest DNA repair and programmed cell death allowing it to halt the progression of damaged cells and trigger repair mechanisms or eliminate those that cannot be repaired.

Pathways

P53 acts within several key biological pathways such as the p53 signaling pathway and the intrinsic apoptotic pathway. Its activity involves interaction with proteins like MDM2 which regulates p53 through ubiquitin-mediated degradation and ATM kinase which phosphorylates p53 in response to DNA damage. These interactions ensure appropriate cellular responses during stress and are vital for maintaining homeostasis.

P53 mutation or inactivation is often associated with the development of cancer given its role in controlling cell division and preventing tumor formation. Specifically its dysfunction has been linked to cancers such as breast cancer and lung cancer. Additionally p53 can interact with other mutant proteins like Ras compounding mutations that contribute to tumor progression and aggressive cancer phenotypes. Understanding these interactions and the status of p53 can be important in developing targeted cancer therapies.

Target data

Multifunctional transcription factor that induces cell cycle arrest, DNA repair or apoptosis upon binding to its target DNA sequence (PubMed : 11025664, PubMed : 12524540, PubMed : 12810724, PubMed : 15186775, PubMed : 15340061, PubMed : 17317671, PubMed : 17349958, PubMed : 19556538, PubMed : 20673990, PubMed : 20959462, PubMed : 22726440, PubMed : 24051492, PubMed : 24652652, PubMed : 35618207, PubMed : 36634798, PubMed : 38653238, PubMed : 9840937). Acts as a tumor suppressor in many tumor types; induces growth arrest or apoptosis depending on the physiological circumstances and cell type (PubMed : 11025664, PubMed : 12524540, PubMed : 12810724, PubMed : 15186775, PubMed : 15340061, PubMed : 17189187, PubMed : 17317671, PubMed : 17349958, PubMed : 19556538, PubMed : 20673990, PubMed : 20959462, PubMed : 22726440, PubMed : 24051492, PubMed : 24652652, PubMed : 38653238, PubMed : 9840937). Negatively regulates cell division by controlling expression of a set of genes required for this process (PubMed : 11025664, PubMed : 12524540, PubMed : 12810724, PubMed : 15186775, PubMed : 15340061, PubMed : 17317671, PubMed : 17349958, PubMed : 19556538, PubMed : 20673990, PubMed : 20959462, PubMed : 22726440, PubMed : 24051492, PubMed : 24652652, PubMed : 9840937). 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 (PubMed : 12524540, PubMed : 17189187). Its pro-apoptotic activity is activated via its interaction with PPP1R13B/ASPP1 or TP53BP2/ASPP2 (PubMed : 12524540). However, this activity is inhibited when the interaction with PPP1R13B/ASPP1 or TP53BP2/ASPP2 is displaced by PPP1R13L/iASPP (PubMed : 12524540). 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 seems to have an 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. Regulates the circadian clock by repressing CLOCK-BMAL1-mediated transcriptional activation of PER2 (PubMed : 24051492).
