Chromatin discovery
WebChromatin immunoprecipitation (ChIP) is a valuable method to investigate protein-DNA interactions in vivo. Since its discovery it has been indispensable to identify binding sites and patterns of a variety of DNA-interacting proteins, such as transcription factors and regulators, modified histones, and epigenetic modifiers. WebBivalent Chromatin. A bivalent chromatin mark consisting of regions harboring stretches of both H3 lysine 27 trimethylation (associated with repression) and H3 lysine 4 trimethylation (associated with activation) modifications serves to poise key developmental genes for lineage-specific activation or repression in ES cells (Bernstein et al., 2006).
