Transcriptional control of gene expression in skeletal muscle cell is involved in different processes ranging from muscle formation to regeneration. The identification of an increasing number of transcription factors, co-factors, and histone modifications has been greatly advanced by methods that allow studies of genome-wide chromatin-protein interactions. Chromatin immunoprecipitation with massively parallel DNA sequencing, or ChIP-seq, is a powerful tool for identifying binding sites of TFs/co-factors and histone modifications. The major steps of this technique involve immunoprecipitation of fragmented chromatin, followed by high-throughput sequencing to identify the protein bound regions genome-wide. Here, in this protocol, we will illustrate how the entire ChIP-seq is performed using global H3K27ac profiling in myoblast cells as an example.
