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 primed human embryonic stem cells, where it associates with the NANOG transcription factor. 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 non-DNase unmatched - State 24:Quies, heterochromatin/dead zone) and K562 erythroleukemia cells (group: K562 Activating non-DNase unmatched - State 24:Quies).
