Histone acetylation and methylation are important regulators of gene activity. Chromatin immunoprecipitation (ChIP or ChrIP) has made it possible to examine not only the state of histone acetylation at a gene but also that of histone methylation and may soon be extended to other histone modifications such as phosphorylation and ubiquitination. In principle such studies are possible as long as an antibody is available to the particular histone modification. Once a target gene is identified it is instructive to see the effect of mutating putative enzymes responsible for the modification to determine how a particular enzyme is responsible for altering chromatin of that gene. Although specific target genes have been studied that contain such modifications recent technical advances have made it possible to study histone modifications genomewide. This not only allows for alternate views of particular paradigms to be investigated, but also uncovers chromosomal patterns of histone modification that would be missed in analyzing individual genes. We describe here an approach to rapidly study histone modifications genomewide by combining chromatin immunoprecipitation and DNA microarrays.
