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 is marked by the H3K4me1 histone modification. 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 K562 erythroleukemia cells (group: K562 Activating non-DNase unmatched - State 4:PromP, inactive/poised promoter, highly conserved).
