DNA methyltransferase-based single-molecule (MAPit) assay for mapping protein-DNA interactions
(Santhi Pondugula, Vamsi K. Gangaraju, Blaine Bartholomew and Michael P.Kladde)
This protocol describes a DNA methyltransferase-based single-molecule (MAPit) assay for mapping protein-DNA interactions in vitro'. MapIt can be used to footprint a variety of protein-DNA interactions, including nucleosomes, transcription factors and engaged polymerases. Here, they describe the application of this method to map nucleosome positions in biochemically reconstituted chromatin preparations either directly or after remodeling with the prototypical yeast ISW2 complex purified from budding yeast. This method should provide a powerful new approach for exploring mechanistic aspects of chromatin remodelling.
