A number of studies have demonstrated that various components of the ATRX/DAXX/Histone H3.3 complex are important for heterochromatin silencing at multiple genomic regions. We provide an overview of the individual components (ATRX, DAXX and/or H3.3) tested in each study and propose a model where the ATRX/DAXX chaperone complex deposits H3.3 to maintain the H3K9me3 modification at heterochromatin throughout the genome.
