Title: Identification of transcription factor binding sites from ChIP-seq data at high-resolution      
dateReleased:
02-06-2014
description:
Genome-wide mapping of protein–DNA interactions is essential for a full understanding of transcriptional regulation. A precise map of binding sites for transcription factors, core transcriptional machinery is vital for deciphering the gene regulatory networks that underlie various biological processes. Chromatin immunoprecipitation followed by sequencing (ChIP–seq) is a technique for genome-wide profiling of DNA-binding proteins. However, our conventional ChIP–seq occasionally gives wider peaks which might be due to overlapping binding sites of two or more transcription factors. Therefore, to improve the resolution of our conventional ChIP–seq which have DNA-protein footprint of ~100 bp, we decreased the size of DNA-protein footprint to ~ 50 bp by DNaseI digestion of whole cell extract (WCE).
