Gene transcription can be regulated through alteration of chromatin structure, such as changes in nucleosome positioning and histone-modification patterns. Recent development of techniques based on the next-generation sequencing technology has allowed high-resolution analysis of genome-wide distribution of these chromatin features. In this chapter, we describe in detail the protocols of ChIP-Seq and MNase-Seq, which have been developed to detect the genome-wide profiles of transcription factor binding, histone modifications, and nucleosome occupancy. We also describe RNA-Seq protocols used to map global gene expression profiles.
