CRISPRi-FlowFISH-validated KLF1 and PRDX2 regulatory element
RGD ID:
38611179
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 the KLF1 (Kruppel like factor 1) gene, and as a negatively-acting element for PRDX2 (peroxiredoxin 2), based on CRISPR/Cas9-mediated perturbation (CRISPRi-FlowFISH method) in K562 erythroleukemia cells.
