      Applications
      Application ReferencesEpitope Identification O'Connor. P., NCI, personal communication
      Key Applications Immunoblotting (Western Blotting)
      Immunoprecipitation
      Application NotesImmunoblotting (3 µg/ml, chemiluminescence)
      Immunoprecipitation (2 µg/sample)
      Application CommentsMaximal p21 WAF1 expression requires wild type p53 activity. Treatment of mouse or rat embryo fibroblasts with DNA damaging agents such as actinomycin D induces wild type p53 expression which in turn activates WAF1 expression. Serum stimulation of quiescent cells will give low level WAF1 expression independent of p53 expression. This antibody can co-precipitate proteins associated with WAF1. Antibody should be titrated for optimal results in individual systems.

      DescriptionPurified mouse monoclonal antibody. Recognizes ~21 kDa p21WAF1 protein.
      BackgroundThe tumor suppressor p53 transcriptionally activates a number of genes including the WAF1/CIP1 gene in response to DNA damage. The 21 kDa product of the WAF1 gene is found in a complex involving cyclins, cyclin dependent kinases (CDK), and PCNA in normal cells but not transformed cells and appears to be a universal inhibitor of CDK activity. One consequence of p21 WAF1 binding to and inhibiting CDKs is to prevent CDK-dependent phosphorylation and subsequent inactivation of the Rb protein which is essential for cell cycle progression. p21 WAF1 is, therefore, a potent and reversible inhibitor of cell cycle progression at both the G1 and G2 checkpoints (2,3,9), presumably to allow sufficient time for DNA repair to be completed. Irreversible G1 or G2 arrest leads to apoptosis. However, the role of p21 WAF1 in apoptosis is less clear although p53-mediated apoptosis leads to increased WAF1 expression. Induction of p21 WAF1 in response to DNA damage can occur by both p53-dependent and p53-independent mechanisms, in response to mitogenic stimuli, differentiation, or in tumor cells with mutated p53. Functional p21 WAF1 is essential for p53-mediated G1 arrest presumably due to WAF1 inhibition of both CDK activity and PCNA-dependent DNA replication. WAF1 has also been identified as a gene involved in cellular senescence, termed sdi1. Not surprisingly, p21 WAF1 overexpression is growth suppressive consistent with its role as an inhibitor of CDKs. By inhibiting Rb inactivation in a p53-dependent fashion, p21 WAF1 serves to integrate cell cycle control mediated by p53 and Rb.
