SMCHD1 Merges Chromosome Compartments and Assists Formation of Super-Structures on the Inactive X.

Abstract excerpt

Mammalian chromosomes are partitioned into A/B compartments and topologically associated domains (TADs). The inactive X (Xi) chromosome, however, adopts a distinct conformation without evident compartments or TADs. Here, through exploration of an architectural protein, structural-maintenance-of-chromosomes hinge domain containing 1 (SMCHD1), we probe how the Xi is reconfigured during X chromosome inactivation....
