| + | [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> | ||

| + | Biogenesis of eukaryotic box C/D small nucleolar ribonucleoproteins initiates co-transcriptionally and requires the action of the assembly machinery including the Hsp90/R2TP complex, the Rsa1p:Hit1p heterodimer and the Bcd1 protein. We present genetic interactions between the Rsa1p-encoding gene and genes involved in chromatin organization including RTT106 that codes for the H3-H4 histone chaperone Rtt106p controlling H3K56ac deposition. We show that Bcd1p binds Rtt106p and controls its transcription-dependent recruitment by reducing its association with RNA polymerase II, modulating H3K56ac levels at gene body. We reveal the 3D structures of the free and Rtt106p-bound forms of Bcd1p using nuclear magnetic resonance and X-ray crystallography. The interaction is also studied by a combination of biophysical and proteomic techniques. Bcd1p interacts with a region that is distinct from the interaction interface between the histone chaperone and histone H3. Our results are evidence for a protein interaction interface for Rtt106p that controls its transcription-associated activity. | ||
