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 a functional repressive element by the Sharpr-MPRA technique (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 12:CtcfO, distal CTCF/candidate insulator with open chromatin).
