CTCFexplorer is a curated data resource encompassing 2,097 high-quality human CTCF ChIP-seq datasets from NCBI GEO across 359 human cell types, and 1,345 high-quality mouse CTCF ChIP-seq datasets across 285 mouse cell types. We identified 531,851 high-confidence and 24,614 constitutive CTCF binding sites in human, and 297,825 high-confidence and 14,925 constitutive CTCF binding sites in mouse. With its systematic approach and user-friendly interface, CTCFexplorer provides an invaluable resource for advancing research in 3D genomics and gene regulation across both species.
CTCFexplorer is implemented in Python and SQL and developed by the Chongzhi Zang Lab at the University of Virginia.
