Summary
Enables protein homodimerization activity. Involved in inactivation of X chromosome by heterochromatin assembly. Acts upstream of or within dosage compensation by inactivation of X chromosome. Located in Barr body. Is expressed in several structures, including blastocyst 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, Apr 2022]
Expression

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
