Regulation of ISWI involves inhibitory modules antagonized by nucleosomal epitopes
2012
Two separate regulatory regions on the Drosophila chromatin remodeller ISWI are defined, AutoN and NegC, which negatively regulate ATP hydrolysis and the coupling of ATP hydrolysis to productive DNA translocation, respectively; epitopes on nucleosomes activate ISWI by inhibiting these negative regulatory domains, ensuring that remodelling occurs only in the appropriate chromatin context.
