CRISPRi-FlowFISH-validated JUNB and PRDX2 regulatory element 1
RGD ID:
38614318
Description:
This genomic region was predicted to be an enhancer based on an activity-by-contact (ABC) model that predicts enhancer-gene connections, where the putative enhancer strength is measured by DNase I hypersensitivity and H3K27 acetylation, and the contact frequency by Hi-C. It was validated as a positively-acting cis-regulatory element for both the JUNB (JunB proto-oncogene, AP-1 transcription factor subunit) and PRDX2 (peroxiredoxin 2) genes based on CRISPR/Cas9-mediated perturbation (CRISPRi-FlowFISH method) in K562 erythroleukemia cells. This locus also includes two accessible chromatin subregions that were validated as silencers based on their ability to repress an origin of replication minimal core promoter by the ATAC-STARR-seq (assay for transposase-accessible chromatin with self-transcribing active regulatory region sequencing) massively parallel reporter assay (MPRA) in GM12878 lymphoblastoid cells.
