From: Zebrafish promoter microarrays identify actively transcribed embryonic genes
H3K4Me3 is enriched at the 5' end of ubiquitously expressed genes but not enriched at non-expressed genes. (a) Examples of genes marked by H3K4Me3 showing a peak of enrichment at the 5'end of the gene. (b) Examples of non-expressed genes that are not marked by H3K4Me3. For (a) and (b) plots show unprocessed ChIP-enrichment ratios for all probes within a genomic region. The chromosomal position (based on Zv4 genome assembly annotation) and the transcription start site and direction of transcription for each gene are shown below each graph. The x-axes are not to scale.
