Smchd1 Gene Summary [Mouse]
Enables ATP hydrolysis activity and protein homodimerization activity. Acts upstream of or within autosome genomic imprinting; inactivation of paternal X chromosome by genomic imprinting; and random inactivation of X chromosome. Located in Barr body. Is expressed in several structures, including blastocyst; early embryo; and genitourinary system. Human ortholog(s) of this gene implicated in facioscapulohumeral muscular dystrophy 2. Orthologous to human SMCHD1 (structural maintenance of chromosomes flexible hinge domain containing 1). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Smchd1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
