CRISPRi-validated cis-regulatory element chr3.3677
RGD ID:
38603848
Description:
This genomic region represents a DNase I hypersensitive site (DHS) that was predicted to be an enhancer by the ENCODE (ENCyclopedia Of DNA Elements) project based on various combinations of H3K27 acetylation and binding of p300, GATA1 and RNA polymerase II in K562 erythroleukemia cells. It was validated as a high-confidence cis-regulatory element for the GATA2 (GATA binding protein 2) gene on chromosome 3 based on multiplex CRISPR/Cas9-mediated perturbation in K562 cells. A subregion was also shown to be an enhancer by the ChIP-STARR-seq massively parallel reporter assay in naive and primed human embryonic stem cells, where it is marked by the H3K27ac and H3K4me1 histone modifications.
