SMCHD1 (Structural Maintenance of Chromosomes Hinge Domain-containing protein 1) is a chromatin-associated protein critical for maintaining genome architecture and regulating gene expression. Discovered in 2008. it belongs to the SMC protein superfamily, known for roles in chromosome organization. SMCHD1 facilitates long-range chromatin interactions and represses gene clusters through epigenetic mechanisms, particularly at imprinted loci and during X chromosome inactivation (XCI). It achieves this by promoting higher-order chromatin compaction, enabling allele-specific gene silencing without altering DNA sequence. Notably, SMCHD1 mutations are linked to facioscapulohumeral muscular dystrophy (FSHD) and Bosma arhinia microphthalmia syndrome (BAMS). In FSHD, loss-of-function mutations derepress the DUX4 retrogene, triggering muscle degeneration. Conversely, BAMS arises from gain-of-function mutations causing craniofacial developmental defects. Recombinant human SMCHD1 protein, typically produced in mammalian or insect cell systems, retains structural integrity for studying its ATPase-dependent chromatin remodeling activities. Current research focuses on exploiting SMCHD1's epigenetic regulatory capacity for therapeutic interventions, particularly in FSHD, where modulating SMCHD1 levels could restore DUX4 silencing while balancing global gene expression impacts.
