Histone variant H2A.Z is crucial for early replication origins licensing and activation in which SUV420H1 preferentially recognizes H2A.Z-nucleosome and deposits H4 lysine 20 dimethylation (H4K20me2) on replication origins. Here, we report the cryo-EM structures of SUV420H1 bound to H2A.Z-nucleosome or H2A-nucleosome and demonstrate that SUV420H1 directly interacts with H4 N-terminal tail, the DNA, and the acidic patch in the nucleosome. The H4 (1-24) forms a lasso-shaped structure that stabilizes the SUV420H1-nucleosome complex and precisely projects the H4K20 residue into the SUV420H1 catalytic center. In vitro and in vivo analyses reveal a crucial role of the SUV420H1 KR loop (residues 214-223), which lies close to the H2A.Z-specific residues D97/S98, in H2A.Z-nucleosome preferential recognition. Together, our findings elucidate how SUV420H1 recognizes nucleosomes to ensure site-specific H4K20me2 modification and provide insights into how SUV420H1 preferentially recognizes H2A.Z nucleosome. | |||||||||
