Description
Function: Heterochromatin component that specifically recognizes and binds methylated 'Lys-9' of histone H3 (H3K9me) and promotes recruitment of proteins that mediate epigenetic repression (PubMed:20871592, PubMed:26022416). Mediates recruitment of the HUSH complex to H3K9me3 sites: the HUSH complex is recruited to genomic loci rich in H3K9me3 and is probably required to maintain transcriptional silencing by promoting recruitment of SETDB1, a histone methyltransferase that mediates further deposition of H3K9me3 (PubMed:26022416). Binds H3K9me and promotes DNA methylation by recruiting DNMT3A to target CpG sites; these can be situated within the coding region of the gene (PubMed:20871592). Mediates down-regulation of CDH1 expression (PubMed:20871592).
Subunit Structure: Homodimer (PubMed:21419134, PubMed:22022377, PubMed:22086334). Interacts (via chromo domain) with histone H3K9me3 (PubMed:20871592). Has the highest affinity for H3K9me3, and lesser affinity for H3K9me2 and H3K9me1 (PubMed:20871592). Component of the HUSH complex; at least composed of FAM208A/TASOR, PPHLN1 and MPHOSPH8 (PubMed:26022416). Interacts with DNMT3, EHMT1 and SETDB1 (PubMed:20871592, PubMed:22086334).
Post-translational Modifications: Phosphorylated in M (mitotic) phase. Phosphorylation by CDK1 promotes dissociation from chromatin.
Similarity: The chromo domain mediates interaction with methylated 'Lys-9' of histone H3 (H3K9me), with the highest affinity for the trimethylated form (H3K9me3)
