UniBind

UniBind provides a comprehensive map of direct transcription factor–DNA interactions by uniformly processing ChIP-seq datasets to produce high-confidence TF binding sites and cis-regulatory modules across multiple species.

Key Features:

• High-quality TFBS predictions: Contains over 56 million predicted transcription factor binding sites covering interactions for 644 transcription factors across more than 1,000 cell lines and tissues.
• Cis-regulatory modules: Predicts over 198,000 cis-regulatory modules representing genomic clusters of TFBSs.
• Evolutionary conservation and functional enrichment: Predicted TFBSs show evolutionary conservation and enrichment at active cis-regulatory regions.
• Combinatorial binding insights: Supports identification of combinatorial binding events where multiple TFs interact with DNA concurrently.
• Cell type and tissue specificity: Correlates enhancer activity specificity with the number of predicted TFBSs in genomic regions.
• Uniform processing and quality control: Derived from the uniform processing of approximately 10,000 public ChIP-seq datasets with rigorous quality control.

Scientific Applications:

• Regulatory element identification: Enables identification of key regulatory elements involved in specific cellular processes based on TFBS and cis-regulatory module predictions.
• Tissue-specific gene regulation: Supports studies of the molecular basis of tissue-specific gene expression by linking TF binding patterns to enhancer activity.
• Evolutionary regulatory analysis: Facilitates investigation of evolutionary conservation of regulatory mechanisms through conserved TFBSs.

Methodology:

Approximately 10,000 public ChIP-seq datasets from nine species were uniformly processed using the ChIP-eat software with rigorous quality control to generate TFBS and cis-regulatory module predictions.
