Figure 3.

Representative trajectories of HP1α on nucleosomes. (A) The construct used is shown. One CD is bound on the trimethylated “A-proximal H3K9,” and the other CD is free at the initial conformation. The other three H3K9s are assumed to be unmethylated. (B) Time courses of the distances from the free CD to three H3K9s are plotted. (C) A close-up view of a time window in (B) is shown, in which two snapshots depicted in (E) occur. (D) For a mononucleosome without linker DNA, the time course of the distance between the free CD and the A-distal H3K9 is shown. To see this figure in color, go online.
