Pioneering transcription factor
Pioneer factors are transcription factors that can directly bind condensed chromatin. They can have positive and negative effects on transcription and are important in recruiting other transcription factors and histone modification enzymes as well as controlling DNA methylation. They were first discovered in 2002 … Visa mer Pioneer factors can also actively affect transcription by directly opening up condensed chromatin in an ATP-independent process. This is a common trait of fork head box factors (which contain a winged … Visa mer Pioneer factors can exhibit their greatest range of effects on transcription through the modulation of epigenetic factors by recruiting activating … Visa mer Pioneer factors can function passively, by acting as a bookmark for the cell to recruit other transcription factors to specific genes in condensed chromatin. This can be important for … Visa mer The ability of pioneer factors to respond to extracellular signals to differentiate cell type has been studied as a potential component of hormone-dependent cancers. Hormones … Visa mer Webb22 jan. 2014 · “Pioneering” transcription factors open certain chromatin domains for regulatory complexes. Novel, genome-wide results establish FoxA1, Hnf4α and AP-2α as pioneer factors for the androgen-receptor in prostate, kidney, and epididymis, respectively. Distinct pioneer/licensing factors guide androgen receptor binding to chromatin.
