The human Polycomb-like protein PHF1 has been implicated in transcription-regulatory and DNA damage repair pathways. A new study demonstrates that the Tudor domain of PHF1 binds histone H3K36me3 with high specificity and affinity, that Tudor-H3K36me3 interaction inhibits Polycomb repressive complex 2-mediated H3K27 methylation and that PHF1 accumulates at DNA damage sites in a Tudor-dependent manner.
