| Enhancer experiment: | ChIP-seq,4C-seq | |
| Enhancer experiment description: | To investigate the correlation between the activity of the Krox20 cis-regulatory elements and their chromatin modifications and conformation, we first performed ChIP-seq experiments to analyse two histone modifications: H3K4me1 (broad peaks covering active enhancers) and H3K27ac (punctuated peaks covering active enhancers and promoters).In E8.5 wild type embryo heads, a number of H3K4me1 peaks were observed, including those that expectedly correspond to the A, B and C elements and to a previously known neural crest element (NCE; Fig 4A). |
About Target gene
| Target gene : | Egr2(AT591,CHN1,CMT1D,CMT4E,KROX20) | |
| Strong evidence: | 4C-seq | |
| Less strong evidence: | -- | |
| Target gene experiment description: | To better characterize the Krox20 regulatory neighborhood, we used circular chromosome conformation capture (4C-seq) on multiple viewpoints in the locus. In samples prepared from total embryos at embryonic day (E) 9.5, when Krox20 is no more transcribed, the Krox20 gene and its distant regulatory element A (separated by over 200 kb) show highly similar distributions of 4C-seq signal (Fig 3A and S2B and S2C Fig) preferentially located in the Krox20 TAD. |

About Function
| Enhancer function : | Enhancer element C possesses a dual activity: besides its classical Enhancer function, it is also permanently required in cis to potentiate the autoregulatory activity of element A, by increasing its chromatin accessibility. |
| Enhancer function experiment: | ChIP-seq |
| Enhancer function experiment description: |
Here, using both enhancer knock-outs and investigations of chromatin organisation, we show that element C possesses a dual activity: besides its classical enhancer function, it is also permanently required in cis to potentiate the autoregulatory activity of element A, by increasing its chromatin accessibility. |
