[https://www.uniprot.org/uniprot/RT106_YEAST RT106_YEAST] Histones H3 and H4 chaperone involved in the nucleosome formation and heterochromatin silencing. Required for the deposition of H3K56ac-carrying H3-H4 complex onto newly-replicated DNA. Plays a role in the transcriptional regulation of the cell-cycle dependent histone genes by directly recruiting the SWI/SNF and RSC chromatin remodeling complexes to the histone genes in a cell cycle dependent manner. In cooperation with HIR and ASF1, creates a repressive structure at the core histone gene promoter and contributes to their repression outside of S phase. Involved in regulation of Ty1 transposition.<ref>PMID:11779788</ref> <ref>PMID:16157874</ref> <ref>PMID:17410207</ref> <ref>PMID:19683497</ref> <ref>PMID:20188666</ref> <ref>PMID:21763693</ref> <ref>PMID:22156209</ref> <ref>PMID:21444721</ref> <ref>PMID:21698254</ref> <ref>PMID:21978826</ref> <ref>PMID:22128187</ref> <ref>PMID:20007951</ref>

Rtt106p is a Saccharomyces cerevisiae histone chaperone with roles in heterochromatin silencing and nucleosome assembly. The molecular mechanism by which Rtt106p engages in chromatin dynamics remains unclear. Here, we report the 2.5 A crystal structure of the core domain of Rtt106p, which adopts an unusual "double pleckstrin homology" domain architecture that represents a novel structural mode for histone chaperones. A histone H3-H4-binding region and a novel double-stranded DNA-binding region have been identified. Mutagenesis studies reveal that the histone and DNA binding activities of Rtt106p are involved in Sir protein-mediated heterochromatin formation. Our results uncover the structural basis of the diverse functions of Rtt106p and provide new insights into its cellular roles.
