WebOct 23, 2024 · How pioneer factors interface with chromatin to promote accessibility for transcription control is poorly understood in vivo. Here, we directly visualize chromatin association by the prototypical GAGA pioneer factor (GAF) in live Drosophila hemocytes. Single-particle tracking reveals that the majority of GAF is chromatin-bound, with a stable … WebThe GAGA factor (GAF) is such a product of the trithorax -like gene, Trl, which binds to a consensus DNA sequence for the modulation of the homeotic gene functions. Besides this, the factor has a role in chromatin remodelling; through binding with the Polycomb responsive element (PRE).
