The protein encoded by this gene contains a leucine-rich repeat and a death domain. This protein has been shown to interact with other death domain proteins, such as Fas (TNFRSF6)-associated via death domain (FADD) and MAP-kinase activating death domain-containing protein (MADD), and thus may function as an adaptor protein in cell death-related signaling processes. The expression of the mouse counterpart of this gene has been found to be positively regulated by the tumor suppressor p53 and to induce cell apoptosis in response to DNA damage, which suggests a role for this gene as an effector of p53-dependent apoptosis. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2010]

WA-1 reacts with human and other mammalian p21, a tumor suppressor protein, belonging to the CDI family. The intracellular protein p21 is a 21 kDa protein, also known as wild-type p53-activated fragment 1 (WAF1). It is an inhibitor of cyclin-dependent kinases (Cdks) and of proliferating-cell nuclear antigen (PCNA). It is induced by wild type p53, but not by mutated p53, by mezerein (anti-leukemic compound) and by interferon-ß. Normal cells generally display a rather intense nuclear p21 expression. Loss of p21 expression has been reported in many carcinomas (gastric carcinoma, non-small cell lung carcinoma and thyroid carcinoma).

This antibody reacts with the C-terminus of Nucleophosmin (B23). NPM1 (Nucleophosmin 1, B23, nutramin, NO38) is a ubiquitously expressed phosphoprotein involved in ribosome assembly/transport, cytoplasmic/nuclear trafficking, regulation of DNA polymerase alpha activity, centrosome duplication, and regulation of p53. NPM1 continuously shuttles between the nucleus, cytoplasm, nucleolus and chaperoning core histones from the nucleus to the cytoplasm.
FR5A10 reacts with CD21, a 140 kDa cell surface molecule which acts as a receptor for EBV, for human complement factor C3d (CR2) and for IFN-alpha. It is a glycoprotein, made up of multiple (n=15) Short Consensus Repeats (S.C.R.) sequences. FR5A10 has been assigned to (S.C.R.) sequences. FR5A10 has been assigned to S.C.R. numbers 5-8. FR5A10 is highly specific to CR2 and shows no cross-reaction with CR1. CD21 is expressed strongly on mature B-cells, follicular dendritic cells and weakly on immature thymocytes and T-lymphocytes. In B-cell ontogeny, CD21 appears after the preB-stage, is maintained during peripheral B-cell development and is lost upon terminal differentiation into plasma cells. CD21 expression is also gradually lost after stimulation of B-cells in vitro.

Bp53-12 reacts with an N-terminal epitope (aa 16-25) of both wild-type and mutated p53. This epitope is revealed in tissue sections only after formalin fixation. Mutation and/or allelic loss of p53 is one of the causes of a variety of mesenchymal and epithelial tumors. p53 Localizes in the nucleus, but is detectable at the plasma membrane during mitosis and when certain mutations modulate cytoplasmic/nuclear distribution.

EBS-I-100 reacts with C. difficile Toxin A, but not with V. cholerae subunit a, V. cholerae toxin, Pseudomonas aeruginosa exotoxin A, H-LT, P-LT. C. difficile is a major nosocomial pathogen that causes antibiotic-associated colitis and mediates inflammatory diarrhea by releasing two large protein enterotoxins (toxin A and toxin B) that are able to disrupt intestinal epithelial cells via their transferase activity and ability to monoglucosylate members of the Rho family. C. difficile toxin A is a toxin that is composed of 39 repeats that are responsible for binding to intestinal epithelial cell surface carbohydrates. C. difficile toxin A causes significant apoptosis of colonocytes which contributes to the formation of ulcers and pseudo-membranes in a pathway that involves p38-dependent activation of p53 and induction of p21, leading to cytochrome c release and caspase-3 activation through Bak activation.

PAb 122 binds to the C-terminus (aa370-378) of both wild type and mutated p53. When microinjected into nuclei, PAb 122 blocked re-entry into the S-phase of the cell cycle. Mutation and/or allelic loss of p53 is one of the causes of a variety of mesenchymal and epithelial tumors. p53 Localizes in the nucleus, but is detectable at the plasma membrane during mitosis and when certain mutations modulate cytoplasmic/nuclear distribution.
p63 is a tumour suppressor protein that is very similar to p53 in structure and function, while being homologous to p73. p63 is important in development and differentiation, and has been identified as a useful marker for distinguishing between lung squamous cell carcinomas and adenocarcinomas. Anti-p63 is also used to differentiate between benign and malignant prostate and breast lesions, due to its labeling of the nuclei of myoepithelial cells in both tissue types.
The gene encoding WAF1, also termed p21, is transcriptionally regulated by the suppressor protein, p53. Overexpression of WAF1 is growth suppressive, possibly by inhibiting the activity of cyclin/CDK complexes. One consequence of WAF1 binding to cyclin/CDK is the inhibition of Rb protein phosphorylation. Induction of WAF1 expression requires wild type p53 activity in cells undergoing p53 dependent G1 arrest or apoptosis. Mutation of the p53 gene is a common event in human cancer and results in the failure to produce WAF1. The effect of this may lead to uncontrolled cell proliferation.

The gene coding for p53 oncoprotein is located on chromosome 17p. Allele loss at this chromosome site has frequently been seen in many tumours including lung, colon, breast and brain. Expression of p53 oncoprotein was not detected in normal mucosa, whereas mutation results in a detectable expression of the p53 protein. It is therefore suggested that immunocytochemical detection of p53 protein is an indication for malignancy. Positive control: Breast carcinoma.
BXP-53 reacts with an internal epitope of bcrp, a 70 kD transmembrane half-transporter which is involved in Multidrug resistance. BXP-53 also reacts with the human BCRP molecule.
The antibody neutralizes mouse interleukin 6 (IL-6). It does not cross-react with LPS (the component of the bacterial cell wall which is considered responsible for the toxicity of gram-negative bacteria) and TNFalpha nor does it block human or rat IL-6 in proliferation assays using the KD83 cell line. MP5-32C11 inhibits mouse IL-6-induced proliferation of the NFS60 myelomonocytic cell line and KD83 plasmacytoma. IL-6 is a pluripotent 20-22 kDa cytokine which plays a role in the pathophysiology of severe infection and regulates the immune response, acute phase reaction and haematopoiesis. IL-6 plays a critical role in Bcell differentiation to plasma cells and is a potent growth factor for plasmacytoma and myeloma. Continuous IL-6 gene expression makes an essential contribution to a multistep oncogenesis of plasma cell neoplasia. IL-6 is a very useful culture supplement for the generation of a high number of antibodyproducing hybridomas.
SV40, Simian Virus 40 is a polyomavirus that is found in both monkeys and humans. Like other polyomaviruses, SV40 is a DNA virus that has the potential to cause tumors. SV40 is believed to suppress the transcriptional properties of tumor-suppressing p53 in humans through the SV40 large T-antigen and SV40 small T-antigen. It is generally assumed that large T-antigen is the major protein involved in neoplastic processes and the large T-antigen predominantly exerts its effect through deregulation of tumor suppressor p53, which is responsible for initiating regulated cell death (apoptosis), or cell cycle arrest when a cell is damaged. A mutated p53 gene may contribute to uncontrolled cellular proliferation, leading to a tumor.

p21 is one of the inhibitors of the phosphorylation of the cyclin-cdk complex. p21, which is an inhibitor of G1 cdks, suppresses the cell cycle and inhibits DNA synthesis. Although p21 is induced by p53 and inhibits cdk (cyclin-dependent kinase) activity, there was virtually no correlation between the expression of p21 and that of p53; this finding was consistent with two reports, though another reported an inverse correlation between the expression of p21 and that of p53. p53independent expression of p21 might account for the discrepancy between the expression of p53 and that of p21. It is expressed in normal human tissue and a wide array of tumors.

p63 is a homolog of the tumor suppressor p53. It is identified in basal cells in the epithelial layers of a variety of tissues, including epidermis, cervix, urothelium, breast and prostate. p63 was detected in nuclei of the basal epithelium in normal prostate glands; however, it was not expressed in malignant tumors of the prostate. As a result, p63 has been reported as a useful marker for differentiating benign from malignant lesions in the prostate, particularly when used in combination with markers of high molecular weight cytokeratins and the prostate-specific marker AMACR (P504S). p63 has also been shown to be a sensitive marker for lung squamous cell carcinomas (SqCC), with a sensitivity of ~90%. Specificity for lung SqCC, vs. lung adenocarcinoma (LADC), is approximately 80%. In breast tissue, p63 has been identified in myoepithelial cells of normal ducts. Pretreatment: Heat induced epitope retrieval in 10 mM citrate buffer, for 20 minutes is required for IHC staining on formalin-fixed, paraffin embedded tissue sections. Note: Dilution of the antibody in 10% normal goat serum followed by a goat anti-mouse secondary antibody-based detection is recommended. Control tissue Breast, Prostate, Prostate carcinoma or lung or bladder squamous cell carcinoma
