Drosophila Rumpelstiltskin regulates Polycomb cis and trans interactions and Homie barrier activity
Three-dimensional genome organization is maintained in part by chromatin insulators, DNA–protein complexes that create boundaries between active and inactive chromatin and regulate enhancer-promoter interactions. In Drosophila, the Homing insulator at eve (Homie) sequence prevents repressive Polycomb (PcG) chromatin at...
