    SUBCELLULAR LOCALIZATION
    basic FUNCTION
  • epigenetic modifier of gene expression that is critical to maintain X chromosome inactivation (Xi)
  • has an important role in CpG island (CGI) methylation on the inactive X chromosome (Xi) and in stable silencing of some Xi genes
  • epigenetic modifier essential for X chromosome inactivation
  • functions to control the expression of essential autosomal genes
  • has a role in the expression of several autosomal gene clusters that are subject to monoallelic expression, rather than being restricted to functioning uniquely in X inactivation

    protein
  • heterochromatin protein 1 (HP1)-binding protein HBiX was required for SMCHD1 localization to H3K9me3 domains
  • is a chromatin repressor involved in the establishment and/or maintenance of CpG methylation at specific loci and binds directly to D4Z4
  • directly binds to D4Z4 and suppresses somatic expression of DUX4
