Transcription factors (TFs) are proteins that bind to DNA and interact with RNA polymerases to regulate gene expression. Some TFs contain a DNA binding domain and can bind directly to specific short DNA sequences ('motifs'); others bind to DNA indirectly through interactions with TFs containing a DNA binding domain. High-throughput antibody capture and sequencing methods (e.g. chromatin immunoprecipitation followed by sequencing, or 'ChIP-seq') can be used to identify regions of TF binding genome-wide. These regions are commonly called ChIP-seq peaks.
The related Transcription Factor ChIP-seq Clusters tracks (hg19, -hg38) +hg38) provide summary views of this data.
The display for this track shows site location with the point-source of the peak marked with a colored vertical bar and the level of enrichment at the site indicated by the darkness of the item. The subtracks are colored by UCSC ENCODE 2 cell type color conventions on the hg19 assembly, and by similarity of cell types in DNaseI hypersensitivity assays (as in the DNase Signal) track in the hg38 assembly.
The display can be filtered to higher valued items, using the Score range: configuration item.
