Description

Chemical modifications (e.g., methylation and acetylation) to the histone proteins present in chromatin influence gene expression by changing how accessible the chromatin is to transcription. A specific modification of a specific histone protein is called a histone mark. This track shows the levels of enrichment of the H3K4Me3 histone mark across the genome as determined by a ChIP-seq assay. The H3K4Me3 histone mark is the tri-methylation of lysine 4 of the H3 histone protein, and it is associated with promoters that are active or poised to be activated. Additional histone marks and other chromatin associated ChIP-seq data is available at the Broad Histone page.

Display Conventions and Configuration

By default, this track uses a transparent overlay method of displaying data from a number of cell lines in the same vertical space. Each of the cell lines in this track is associated with a particular color, and these colors are relatively light and saturated so as to work best with the transparent overlay. The color of these tracks match their versions from their lifted source on the hg19 assembly. The colors are consistent with the other hg19 lifted tracks located in the ENCODE Regulation supertrack, with the exception being the DNase tracks, as they were not lifted from hg19 and are colored to reflect similarity of cell types.

This track shows data from the Bernstein Lab at the Broad Institute, as part of the ENCODE Consortium.

Data Release Policy

Primary ENCODE data produced during the 2007-2012 production phase were subject to a restriction period. However, the data here are past those restrictions and are freely available. The full data release policy for ENCODE is available here.
