Expression data from mutant p53 breast cancer cell line SK-BR-3

Tumor associated mutant p53 proteins often gain new functions for tumorigenesis and tumor progression. It has been shown that mutant p53 can transcriptionally regulate a group of genes, which in turn contributes to mutant p53 gain of function. A mutant p53 interacting protein Pontin binds to mutant p53 and promotes its gain of function. This experiment tests whether the interaction of Pontin with mutant p53 regulates the transcriptional activity of mutant p53.
