H2A.Z, a widely conserved histone variant, is evicted from chromatin by the histone chaperone ANP32E. However, to date, no deposition chaperone for H2A.Z is known in metazoans. Here, we identify YL1 as a specific H2A.Z-deposition chaperone. The 2.7-angstrom-resolution crystal structure of the human YL1-H2A.Z-H2B complex shows that YL1 binding, similarly to ANP32E binding, triggers an extension of the H2A.Z alpha C helix. The interaction with YL1 is, however, more extensive and includes both the extended acidic patch and the entire DNA-binding surface of H2A.Z-H2B. Substitution of only four amino acid residues of H2A is sufficient for the formation of an H2A.Z-like interface specifically recognized by YL1. Collectively, our data reveal the molecular basis of H2A.Z-specific recognition by YL1 and shed light on the mechanism of H2A.Z transfer to the nucleosome by the ATP-dependent chromatin-remodeling complexes SRCAP and P400-TIP60.
