This collection of tracks offers an integrated view of genomic annotations and experimental data from all phases of the ENCODE Project, with a focus on transcriptional regulation. It includes averaged and representative signals from assays that measure chromatin accessibility (DNase-seq and ATAC-seq), transcription factor (TF) binding (ChIP-seq for individual TFs), histone modifications (ChIP-seq for H3K4me3 and H3K27ac), CTCF binding, and transcription (RNA-seq).
These tracks complement one another and collectively provide a powerful resource for interpreting regulatory DNA. Histone marks are broadly informative but have limited resolution (~200 bp) and relatively low functional specificity. DNase-seq assays offer higher resolution and scalability across many cell types, and they reliably indicate regulatory potential, though they lack detailed functional context. ATAC-seq serves a similar role to DNase-seq, with comparable resolution and limitations. Transcription factor ChIP-seq has high positional resolution and, due to the specificity of TFs, often provides more direct functional insight. However, because each TF must be assayed individually, the data are limited in biosample coverage. Despite the individual strengths and limitations of these assays, their independence from one another increases confidence when multiple assays suggest a regulatory function for the same genomic region.

This integrative supertrack presents a curated selection of the most informative and broadly relevant datasets. Further functional annotations of individual regulatory elements are available at SCREEN.
By default, the DNase (Layered), ATAC (Layered), H3K4me3 (Layered), H3K27ac (Layered), CTCF (Layered), and Transcription (Layered) tracks use a transparent overlay to visualize signals from multiple organs or tissues within a single track. For each organ or tissue, signal values from all associated experiments are averaged. Each organ or tissue is assigned a distinct color, selected to be light and saturated to maintain clarity when overlaid. Initially, each layered track displays an overlay of five representative organs: blood, brain, kidney, liver, and muscle. Clicking on the track opens a details page where you can view and select organs or tissues.
For the TF rPeaks track, each rPeak (representative peak) is shown as a gray box, with the shade of gray indicating the maximum ChIP-seq signal for the corresponding TF across all contributing biosamples. The HGNC gene symbol of the TF is displayed to the left of the box when viewed in pack display mode. If the rPeak overlaps a cognate TF motif from a previously curated collection (PMID: 37104580), the motif site is highlighted in green.
The TF ChIP-seq (indiv.), ATAC/DNase/Histone/CTCF (indiv.), and RNA-seq (indiv.) tracks are hidden by default. Clicking on any of these tracks opens a details page where you can select specific biosample-level experiments to display.
The ENCODE 4 Regulation data on the UCSC Genome Browser can be explored interactively with the Table Browser or the Data Integrator. For automated download and analysis, the track data files can be downloaded from our download server or queried using the REST API. Individual regions or the whole genome annotation can be accessed as text using our utilities bigWigToWig and bigBedToBed. Instructions for downloading source code and binaries can be found here. The original data files are also available from the ENCODE portal.
Data were generated by the ENCODE Consortium. The data were further processed for visualization through a collaborative effort between the Weng lab and the Moore lab at UMass Chan Medical School (funded by NIH grant HG012343). Integration and visualization were developed by Drs. Mingshi Gao, Greg Andrews, Jill Moore, and Zhiping Weng at UMass Chan Medical School, who were part of the ENCODE Data Analysis Center.
Users may freely download, analyze, and publish results based on any ENCODE data without restrictions. Researchers using unpublished ENCODE data are encouraged to contact the data producers to discuss possible coordinated publications; however, this is optional.
Users of ENCODE datasets are requested to cite the ENCODE Consortium and ENCODE production laboratory(s) that generated the datasets used, as described in Citing ENCODE.
