A model for extradenticle function as a switch that changes HOX proteins from repressors to activators.
The Drosophila EXD protein and its mammalian counterparts, the PBX proteins, have been proposed to function in HOX target selectivity. Here we show that exd function is required for the autoactivation phase of Dfd expression in the posterior head. Mutations that change the affinity of a small autoactivation element for EXD protein result in corresponding changes in the element's embryonic activ...

متن کاملCharacterization of the p53 Response to Oncogene-Induced Senescence
BACKGROUND P53 activation can trigger various outcomes, among them reversible growth arrest or cellular senescence. It is a live debate whether these outcomes are influenced by quantitative or qualitative mechanisms. Furthermore, the relative contribution of p53 to Ras-induced senescence is also matter of controversy. METHODOLOGY/PRINCIPAL FINDINGS This study compared situations in which diff...
