clone BP53-12, Upstate®, from mouse
The human wild-type p53 protein is a 393 amino acid nuclear phosphoprotein, present in the nucleus of all normal mammalian cells where it appears to be involved in the regulation of cell proliferation. The normal protein has a very short half-life and is present in only minute amounts in normal tissues and cells. In contrast, mutant p53 protein produced by malignant cells is usually a product of a point mutation in the p53 gene leading to substitution of a single amino acid that significantly prolongs the half-life of the protein. The accumulation of high levels of p53 is a potential novel marker for malignancy.
