This genomic sequence was predicted to be a transcriptional regulatory region based on chromatin state analysis from the ENCODE (ENCyclopedia Of DNA Elements) project. The major subregion was validated as an active enhancer by the ChIP-STARR-seq massively parallel reporter assay in naive human embryonic stem cells, where it associates with the NANOG transcription factor. Another subregion was 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 non-DNase unmatched - State 16:ElonW, transcriptional elongation, weaker H3K36me3) and K562 erythroleukemia cells (group: K562 Activating DNase matched - State 5:Enh, candidate strong enhancer, open chromatin).
