Heterochromatin component that specifically recognizes and binds methylated 'Lys-9' of histone H3 (H3K9me) and promotes recruitment of proteins that mediate epigenetic repression. Mediates recruitment of the HUSH complex to H3K9me3 sites: the HUSH complex is recruited to genomic loci rich in H3K9me3 and is required to maintain transcriptional silencing by promoting recruitment of SETDB1, a histone methyltransferase that mediates further deposition of H3K9me3, as well as MORC2. Binds H3K9me and promotes DNA methylation by recruiting DNMT3A to target CpG sites; these can be situated within the coding region of the gene. Mediates down-regulation of CDH1 expression. Also represses L1 retrotransposons in collaboration with MORC2 and, probably, SETDB1, the silencing is dependent of repressive epigenetic modifications, such as H3K9me3 mark. Silencing events often occur within introns of transcriptionally active genes, and lead to the down-regulation of host gene expression. The HUSH complex is also involved in the silencing of unintegrated retroviral DNA by being recruited by ZNF638: some part of the retroviral DNA formed immediately after infection remains unintegrated in the host genome and is transcriptionally repressed.

The haploid screen identified HUSH, an epigenetic heterochromatin repressor complex composed of three subunits, TASOR, MPP8 and Periphilin. (Review)PMID:26853531
findings demonstrate MPP8 and SIRT1 reciprocally regulate each other's function at multiple molecular layers through physical interaction; disruption of MPP8-SIRT1 interaction de-represses E cadherin expression and reduces cell motility and invasiveness suggesting this interplay plays critical role in MPP8- and SIRT1-mediated epithelial-mesenchymal transitionPMID:25870236
this study identified the HUSH (human silencing hub) complex, comprising three poorly characterized proteins, TASOR, MPP8, and periphilin; this complex is absent from Drosophila but is conserved from fish to humans.PMID:26022416
Knockdown analysis of MPP8 in HeLa cells resulted in derepression of a set of genes that are normally expressed in spermatogonia, spermatids and mature sperm, thereby indicating a role for this molecule in silencing testis-related genes in somatic cells.PMID:25660450
interaction of HN with MPP8 may play a role in oncogenesis because MPP8 increases tumor cell motility and invasionPMID:23532874
