H4K20me1 Contributes to Downregulation of X
... The DCC is targeted to the X chromosome through specific sequence elements, called rex (recruitment elements on X) sites (reviewed in [3]). After recruitment, the DCC spreads to dox (dependent on X) sites, which consist mostly of active promoters. The zinc finger protein SDC-2 is the primary X-chrom ...
