Abstract

p53 limits the proliferation of precancerous cells by inducing cell-cycle arrest or apoptosis. How the decision between survival and death is made at the level of p53 binding to target promoters remains unclear. Using cancer cell lines, we show that the cooperative nature of DNA binding extends the binding spectrum of p53 to degenerate response elements in proapoptotic genes. Mutational inactivation of cooperativity therefore does not compromise the cell-cycle arrest response but strongly reduces binding of p53 to multiple proapoptotic gene promoters (BAX, PUMA, NOXA, CASP1). Vice versa, engineered mutants with increased cooperativity show enhanced binding to proapoptotic genes, which shifts the cellular response to cell death. Furthermore, the cooperativity of DNA binding determines the extent of apoptosis in response to DNA damage. Because mutations, which impair cooperativity, are genetically linked to cancer susceptibility in patients, DNA binding cooperativity contributes to p53's tumor suppressor activity.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
