Abstract excerpt
Imitation switch (ISWI)-family remodelling enzymes regulate access to genomic DNA by mobilizing nucleosomes. These ATP-dependent chromatin remodellers promote heterochromatin formation and transcriptional silencing by generating regularly spaced nucleosome arrays. The nucleosome-spacing activity arises from the dependence of nucleosome translocation on the length of extranucleosomal linker DNA, but the underlying...
