  • SETDB1 and HUSH complex suppress Xist transcription during X chromosome inactivation (XCI) establishment by depositing H3K9me3.
  • Depletion of SETDB1 or HUSH subunits increases Xist transcription, RNA accumulation, and accelerates X-linked gene silencing.
  • The SETDB1/HUSH pathway regulates Xist RNA levels to ensure inactivation of only one X chromosome in female cells.
