This genomic sequence was predicted to be a transcriptional regulatory region based on chromatin state analysis from the ENCODE (ENCyclopedia Of DNA Elements) project. Two overlapping subregions were validated as functional enhancers by the Sharpr-MPRA technique (Systematic high-resolution activation and repression profiling with reporter tiling using massively parallel reporter assays) in K562 erythroleukemia cells (group: K562 Activating DNase unmatched - State 14:Gen5', transcription transition, highly expressed genes towards 5' end). One subregion also displayed repressive activity by Sharpr-MRPA in HepG2 liver carcinoma cells (group: HepG2 Repressive DNase matched - State 25:Art, potential CNV or repetitive artifacts).
