| + | [https://www.uniprot.org/uniprot/UBP8_YEAST UBP8_YEAST] Functions as histone deubiquitinating component of the transcription regulatory histone acetylation (HAT) complexes SAGA and SLIK. 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. Together with SGF11, is required for histone H2B deubiquitination.<ref>PMID:10026213</ref> <ref>PMID:14660634</ref> <ref>PMID:15657441</ref> | ||
