The HUSH complex plays a key role in controlling transcription of viruses and transposable elements. Here, the authors define the biochemical basis of HUSH assembly and show that the TASOR subunit contains a pseudo-PARP domain critical for HUSH-dependent transgene repression and H3K9me3 deposition over targets genome wide.
