Target Background

Function(From Uniprot)

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.

Gene References into Functions

an unexpected role for Sgf11 in compensating for the absence of structural features that maintain the active conformation of Ubp8. PMID:22771212
Structural and functional analyses reveal a central role of Sgf11 and Sgf73 in activating Ubp8 for deubiquitinating histone H2B and demonstrate how a DUB can be allosterically regulated by its nonsubstrate partners. PMID:20434206
Ubp8 is a part of the SAGA complex and its deubiquitylation activity requires Ubp8's association with SAGA. PMID:15657442
Ubp8p differential control of H3-K4 methylation is mediated by Sgf11p at the SAGA-dependent promoters. PMID:16611979
Thus, the Sus1-Sgf11-Ubp8 module could work at the junction between SAGA-dependent transcription and nuclear mRNA export. PMID:16855026
