MED14-independent group 3 enhancer GRCh37_chr9:94909356-94910555
RGD ID:
38638065
Description:
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 STARR-seq (self-transcribing active regulatory region sequencing) massively parallel reporter assay (MPRA) in HCT116 colorectal carcinoma cells, where it was defined as a group 3 enhancer that depends on the BRD2, BRD4, P300/CBP and CDK7 cofactors, but it has limited or no dependence on the MED14 core Mediator complex subunit. A subregion was also validated as a functional 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 22:ReprW, weaker Polycomb repression) and K562 erythroleukemia cells (group: K562 Activating DNase unmatched - State 1:Tss, active promoter, TSS/CpG island region). This locus also includes an accessible chromatin subregion that was validated as an enhancer based on its ability to activate an origin of replication minimal core promoter by the ATAC-STARR-seq (assay for transposase-accessible chromatin with self-transcribing active regulatory region sequencing) MPRA in GM12878 lymphoblastoid cells.
