[https://www.uniprot.org/uniprot/CHD1_YEAST CHD1_YEAST] ATP-dependent chromatin-remodeling factor which functions as substrate recognition component of the transcription regulatory histone acetylation (HAT) complexes SAGA and SLIK. It recognizes H3K4me. SAGA is involved in RNA polymerase II-dependent transcriptional regulation of approximately 10% of yeast genes. At the promoters, SAGA is required for recruitment of the basal transcription machinery. It influences RNA polymerase II transcriptional activity through different activities such as TBP interaction (SPT3, SPT8 and SPT20) and promoter selectivity, interaction with transcription activators (GCN5, ADA2, ADA3 and TRA1), and chromatin modification through histone acetylation (GCN5) and deubiquitination (UBP8). SAGA acetylates nucleosomal histone H3 to some extent (to form H3K9ac, H3K14ac, H3K18ac and H3K23ac). SAGA interacts with DNA via upstream activating sequences (UASs). SLIK is proposed to have partly overlapping functions with SAGA. It preferentially acetylates methylated histone H3, at least after activation at the GAL1-10 locus. Acts in opposition to the FACT complex in regulating polymerase II transcription. Also required for efficient transcription by RNA polymerase I, and more specifically the pol I transcription termination step. Regulates negatively DNA replication. Not only involved in transcription-related chromatin-remodeling, but also required to maintain a specific chromatin configuration across the genome.<ref>PMID:10026213</ref> <ref>PMID:10811623</ref> <ref>PMID:12682017</ref> <ref>PMID:14585955</ref> <ref>PMID:15647753</ref> <ref>PMID:16606615</ref> <ref>PMID:16468993</ref> <ref>PMID:17949749</ref> <ref>PMID:17620414</ref> <ref>PMID:17259992</ref> <ref>PMID:18245327</ref>
