Maintenance of epigenetic landscape requires CIZ1 and is corrupted in differentiated fibroblasts in long-term culture
Abstract
The inactive X chromosome (Xi) is a model for establishment and maintenance of repressed chromatin and the function of polycomb repressive complexes. Here the authors show that Xi transiently relocates from the nuclear periphery during replication in a CIZ1-dependent manner, which plays a role in maintaining PRC-mediated repressed chromatin.
