Opis ogólny
p53 was discovered in 1979 as a cellular protein associating with the transforming protein of SV40 tumor virus. Since then, many different biochemical functions have been attributed to the 53 kD phosphoprotein. Experimental evidence has suggested that p53 acts as a negative regulator of cell growth in normal cells (Finlay, 1989). Thus, the inactivation or mutation of p53 may be an essential step in the development of malignancy (Lane and Benchmol, 1990). Wild-type p53 levels in normal cells and tissues were found to be very low. Mutant p53 polypeptide, however, is often found to be present at high concentrations in mammalian tumors and tumor cell lines. For example, in an immuno-histochemistry study 40% of human breast cancer showed elevated levels of mutant p53 in the cell nucleus. Mutations of the p53 protein have some characteristic features:
a) Most of them are missense point mutations giving rise to an altered protein function.
b) Many -but not all- mutant p53 proteins exhibit a common mutant structure, which can be recognized by monoclonal antibodies specific for p53 in the mutant conformation.

Specyficzność
PAb 240 recognizes an epitope of p53 tumor suppressor protein between amino acids 211 and 220 (Gannon, 1990; Legros, 1994) in human, mouse, rat, hamster, monkey, cow and chicken. Assaying native samples (immunoprecipitation, ELISA) the PAb 240 detects only the mutant forms of p53 (Gannon, 1990; Said, 1994). In methods using denatured samples [Western blot analysis (Gannon, 1990) and immunohistochemistry of frozen tissue sections (Said, 1994; Bartek, 1991; Walker, 1991)], the PAb 240 recognizes both mutant and denatured wild-type p53.

Mutant (Mt) p53 abrogates tumor suppression functions of wild-type (WT) p53 through mutant-specific, gain-of-function effects, and patients bearing Mt p53 are chemoresistant. The dominant negative effect of p53 mutants results from their aggregation propensity which causes co-aggregation of WT p53.
