Periphilin-1 (PPHLN1)

Component of the HUSH complicated, a multiprotein complex that mediates epigenetic repression. The HUSH complex is recruited to genomic loci full of H3K9me3 and is probably required to maintain transcriptional silencing by encouraging recruitment of SETDB1, a histone methyltransferase that mediates further deposition of H3K9me3.

In the HUSH complex, contributes to the upkeep of the complex at chromatin (PubMed:26022416). Acts as a transcriptional corepressor and modulates the cell cycle, probably through the HUSH complicated (PubMed:15474462, PubMed:17963697).
