This genomic region was predicted to be a cell type-specific enhancer based on chromatin state analysis from the ENCODE (ENCyclopedia Of DNA Elements) project. It was validated as a functional enhancer by high-throughput massively parallel reporter assays (MPRAs) in liver carcinoma HepG2 cells. This enhancer contains a motif for the HNF4 activator. Mutation of this motif results in reduced enhancer activity. [provided by RefSeq, Dec 2017]
