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 human embryonic stem cells, where it associates with the OCT4 and NANOG transcription factors and is marked by the H3K27ac histone modification. A subregion was also validated as a repressive element by Sharpr-MPRA (Systematic high-resolution activation and repression profiling with reporter tiling using massively parallel reporter assays) in HepG2 liver carcinoma cells (group: HepG2 Repressive non-DNase unmatched - State 24:Quies, heterochromatin/dead zone).
