Chromatin Interactions

Three-dimensional chromatin interaction maps aggregated from major consortia and specialized studies, capturing promoter-enhancer contacts, topological domain boundaries, and long-range regulatory links. Coverage spans primary cells, cell lines, and tissues across adult and embryonic samples, with strong representation of blood, brain, and digestive tissues.

Methods

Data in this track hub were uniformly downloaded, processed, and harmonized by FILER2. Raw files were obtained from each source repository, converted to BED/bigBed format, lifted to the target genome assembly where necessary, and annotated with standardized metadata including cell type, tissue category, and assay type.
