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 primed human embryonic stem cells, where it associates with the OCT4 and NANOG transcription factors and is marked by the H3K27ac and H3K4me1 histone modifications. 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 HepG2 liver carcinoma cells (group: HepG2 Activating DNase matched - State 4:PromP, inactive/poised promoter, highly conserved).
