Figure Lengend Snippet: Chromatin 3D structures. Shown is a two-dimensional heatmap of Hi-C interaction frequencies in IMR90 cells from a 5 MB region of Chr2 generated using the website: http://www.3dgenome.org and the color key represents the interaction counts between two loci. Highlighted in gray is a repressed compartment and highlighted in orange is an active compartment. Also shown is ChIP-seq data for CTCF and histone modifications, as well as a wavelet-smoothed Repli-seq track representing DNA replication timing; all datasets were taken from the University of California, Santa Cruz genome browser. For each compartment, a model of chromatin interactions is shown (which are more frequent within a TAD than between TADs) facilitated by CTCF, Cohesin, and Mediator. Long-distance constitutive interactions require a pair of CTCF sites with convergently orientated motifs as anchors; any combination of CTCF, cohesin, and mediator can facilitate median distance interactions. Many other CTCF-binding sites (green bars) are not involved in chromatin interactions and occur within loops. (see the color version of this figure at www.informahealthcare.com/bmg ).
