Mapping global histone methylation patterns in the coding regions of human genes.

ABSTRACT: Histone methylation patterns in the human genome, especially in euchromatin regions, have not been systematically characterized. In this study, we examined the profile of histone H3 methylation (Me) patterns at different lysines (Ks) in the coding regions of human genes by genome-wide location analyses by using chromatin immunoprecipitation linked to cDNA arrays. Specifically, we compared H3-KMe marks known to be associated with active gene expression, namely, H3-K4Me, H3-K36Me, and H3-K79Me, as well as those associated with gene repression, namely, H3-K9Me, H3-K27Me, and H4-K20Me. We further compared these to histone lysine acetylation (H3-K9/14Ac). Our results demonstrated that: first, close correlations are present between active histone marks except between H3-K36Me2 and H3-K4Me2. Nota
