Strong evidence: | -- |
Less strong evidence: | PCR |
Target gene experiment description: | The regions that we analyzed were the HBG-4kb HS,a 327 region located 4 kb upstream (HBG-8kb) or 1 and 2 kb downstream(HBG-3kb and HBG-2kb) of 328 the HBG-4kb HS,the G?-(HBG2) and A?-(HBG1) globin gene promoter regions.;The regions that we analyzed were the HBG-4kb HS,a 327 region located 4 kb upstream (HBG-8kb) or 1 and 2 kb downstream(HBG-3kb and HBG-2kb) of 328 the HBG-4kb HS,the G?-(HBG2) and A?-(HBG1) globin gene promoter regions.;The regions that we analyzed were the HBG-4kb HS,a 327 region located 4 kb upstream (HBG-8kb) or 1 and 2 kb downstream(HBG-3kb and HBG-2kb) of 328 the HBG-4kb HS,the G?-(HBG2) and A?-(HBG1) globin gene promoter regions. |

TF experiment: | ChIP |
TF experiment description: | Reduced binding of transcription factors with the HBG-4kb HS in K562 cells expressing the HBG-4kb ZF. K562 cells (Untreated) or K562 cells exposed to 500 nM HBG-4kb ZF for 12 h were subjected to ChIP using antibodies specific for EGR1, USF1, USF2, NF-E2 (p45), MafK, or the negative control, IgG.;Reduced binding of transcription factors with the HBG-4kb HS in K562 cells expressing the HBG-4kb ZF.

Enhancer function : | the HBG-4kb HS site is important for fetal globin production and suggest that it may act by opening chromatin in a directional manner. |
Enhancer function experiment: | CRISPR/Cas9 |
Enhancer function experiment description: |
Expression of the adult ?-globin, the embryonic -globin, and the GATA1 genes was not affected by the HBG-4kb ZF. Delivery of the Control ZF did not cause any change in expression of the ?-globin, ?-globin, -globin, or GATA1 genes. |
