Extended Data Fig. 10: Compartment and TADs in zebrafish.
From: A map of cis-regulatory elements and 3D genome structures in zebrafish
a, Heat map of genome-wide Hi-C interaction matrices in zebrafish brain (blue) and muscle (red). b, Active marks (H3K4me3, H3K27ac, and ATAC-seq) were enriched in compartment A and depleted in compartment B. Repressive marks (H3K9me2 and H3K9me3) were enriched in compartment B. Error bands represent standard error of the mean. c, Genome browser snapshot of A/B compartment in brain and muscle. The blue vertical shaded area marks a region that is located in compartment B in brain but in compartment A in muscle. As expected, A compartment which is associated with more ATAC-seq peaks, H3K27ac and RNA-seq signals. d, Examples of shared TADs between zebrafish brain and muscle. e, Average DI scores surrounding TAD boundaries identified in brain (upper panel) and muscle (lower panel). f, ChIP-seq data shows that CTCF binding sites were enriched at TAD boundaries. g, Footprint analysis of ATAC-seq peaks in the TAD boundaries shows enrichment of CTCF binding motif (number of each bar, from left to right, 0.213, 0.24, 0.22, 0.237, 0.251, 0.232, 0.24, 0.262, 0.271, 0.281, 0.37, 0.27, 0.253, 0.25, 0.252, 0.253, 0.26, 0.23, 0.238, 0.24, 0.22). h, Repetitive elements enriched at TAD boundaries (left panel) and loop anchors (right panel).
