Gene description: H3K27ac-H3K4me1 hESC enhancer GRCh37_chr2:239006826-239007494
Gene type: biological region
This genomic sequence was predicted to be a transcriptional regulatory region based on chromatin state analysis from the ENCODE (ENCyclopedia Of DNA Elements) project. It was validated as an active enhancer by the ChIP-STARR-seq massively parallel reporter assay in naive and primed human embryonic stem cells, where it is marked by the H3K27ac and H3K4me1 histone modifications. A subregion was also validated as an enhancer by Sharpr-MPRA (Systematic high-resolution activation and repression profiling with reporter tiling using massively parallel reporter assays) in both HepG2 liver carcinoma cells (group: HepG2 Activating DNase unmatched - State 18:Pol2, Pol2 specific locations, majority in genes but substantial portion in intergenic locations) and K562 erythroleukemia cells (group: K562 Activating DNase matched - State 5:Enh, candidate strong enhancer, open chromatin).
