Source data
Regulatory features are generated using a variety of genome-wide assays, such as ATAC-seq, DNAase-seq, and ChIP-seq of histone marks and transcription factor binding.
Regulatory features for human and mouse are based on data from the ENCODE project. Annotation for farmed animal and aquaculture species are based on data from different FAANG projects.
All primary data are available in ENA, and are indexed and searchable in the ENCODE or FAANG portals.
