| ID | Symbol | Description | Aliases |
| YDR448W | ADA2 | Transcription coactivator, component of the ADA and SAGA transcriptional adaptor/HAT (histone acetyltransferase) complexes | SWI8 | |
| YOL072W | THP1 | Nuclear pore-associated protein, forms a complex with Sac3p that is involved in transcription and in mRNA export from the nucleus; contains a PAM domain implicated in protein-protein binding | BUD29 | |
| YMR236W | TAF9 | Subunit (17 kDa) of TFIID and SAGA complexes, involved in RNA polymerase II transcription initiation and in chromatin modification, similar to histone H3 | TAF17, TafII17 | |
| YDR159W | SAC3 | Nuclear pore-associated protein, forms a complex with Thp1p that is involved in transcription and in mRNA export from the nucleus | LEP1 | |
| YMR223W | UBP8 | Ubiquitin-specific protease that is a component of the SAGA (Spt-Ada-Gcn5-Acetyltransferase) acetylation complex; required for SAGA-mediated deubiquitination of histone H2B | | |
| YBR111W-A | SUS1 | Protein involved in mRNA export coupled transcription activation; component of the SAGA histone acetylase complex | | |
| YPL047W | SGF11 | Integral subunit of SAGA histone acetyltransferase complex, regulates transcription of a subset of SAGA-regulated genes, required for the Ubp8p association with SAGA and for H2B deubiquitylation | | |
| YLR055C | SPT8 | Subunit of the SAGA transcriptional regulatory complex but not present in SAGA-like complex SLIK/SALSA, required for SAGA-mediated inhibition at some promoters | | |
| YGL112C | TAF6 | Subunit (60 kDa) of TFIID and SAGA complexes, involved in transcription initiation of RNA polymerase II and in chromatin modification, similar to histone H4 | TAF60, TafII60 | |
| YDR392W | SPT3 | Subunit of the SAGA and SAGA-like transcriptional regulatory complexes, interacts with Spt15p to activate transcription of some RNA polymerase II-dependent genes, also functions to inhibit transcription at some promoters | | |
