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 (MPRA) in naive 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 4:PromP, inactive/poised promoter, highly conserved) and K562 erythroleukemia cells (group: K562 Activating DNase unmatched - State 5:Enh, candidate strong enhancer, open chromatin). This locus also includes an accessible chromatin subregion that was validated as an enhancer based on its ability to activate an origin of replication minimal core promoter by the ATAC-STARR-seq (assay for transposase-accessible chromatin with self-transcribing active regulatory region sequencing) MPRA in GM12878 lymphoblastoid cells.
