Methods for Global Characterization of Chromatin Regulators in Human Cells

About this book

Chromatin is a multi-layered structure composed of DNA, nucleosomes, histone modifications, and associated proteins that critically affects genome function. Recently developed sequencing technologies enable genomewide characterization of certain aspects of chromatin structure, including nucleosome positioning and histone modifications. However, chromatin proteins present several challenges due to their dynamic nature and variable association with DNA. Chromatin proteins such as Polycomb regulators and heterochromatic factors play critical and global roles in epigenetic repression and hence new approaches are needed for their study.
