molecular function |
| GO:0008047 | | enzyme activator activity | | Binds to and increases the activity of an enzyme. |
| GO:0004402 | | histone acetyltransferase activity | | Catalysis of the reaction: acetyl-CoA + histone = CoA + acetyl-histone. |
| GO:0005515 | | protein binding | | Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules). |
| GO:0005198 | | structural molecule activity | | The action of a molecule that contributes to the structural integrity of a complex or its assembly within or outside a cell. |
biological process |
| GO:0016573 | | histone acetylation | | The modification of a histone by the addition of an acetyl group. |
| GO:0016578 | | histone deubiquitination | | The modification of histones by removal of ubiquitin groups. |
| GO:0006406 | | mRNA export from nucleus | | The directed movement of mRNA from the nucleus to the cytoplasm. |
| GO:0045899 | | positive regulation of RNA polymerase II transcriptional preinitiation complex assembly | | Any process that activates or increases the frequency, rate or extent of RNA polymerase II transcriptional preinitiation complex assembly. |
| GO:0043085 | | positive regulation of catalytic activity | | Any process that activates or increases the activity of an enzyme. |
| GO:0006461 | | protein complex assembly | | The aggregation, arrangement and bonding together of a set of components to form a protein complex. |
| GO:0006355 | | regulation of transcription, DNA-templated | | Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription. |
| GO:0006351 | | transcription, DNA-templated | | The cellular synthesis of RNA on a template of DNA. |
cellular component |
| GO:0071819 | | DUBm complex | | A protein complex that forms part of SAGA-type complexes SAGA and SLIK, and mediates deubiquitination of histone H2B. In S. cerevisiae, the DUBm consists of the proteins Ubp8p, Sgf11p, Sus1p, and Sgf73p. |
| GO:0000124 | | SAGA complex | | A SAGA-type histone acetyltransferase complex that contains Spt8 (in budding yeast) or a homolog thereof; additional polypeptides include Spt group, consisting of Spt7, Spt3, and Spt20/Ada5, which interact with the TATA-binding protein (TBP); the Ada group, consisting of Ada1, Ada2, Ada3, Ada4/Gcn5, and Ada5/Spt20, which is functionally linked to the nucleosomal HAT activity; Tra1, an ATM/PI-3 kinase-related protein that targets DNA-bound activators for recruitment to promoters; the TBP-associated factor (TAF) proteins, consisting of Taf5, Taf6, Taf9, Taf10, and Taf12, which mediate nucleosomal HAT activity and are thought to help recruit the basal transcription machinery; the ubiquitin specifc protease Ubp-8. |
| GO:0046695 | | SLIK (SAGA-like) complex | | A SAGA-type histone acetyltransferase complex that contains Rtg2 and a smaller form of Spt7 than the fungal SAGA complex, and lacks Spt8. The complex is involved in the yeast retrograde response pathway, which is important for gene expression changes during mitochondrial dysfunction. |
| GO:0005829 | | cytosol | | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. |
| GO:0005634 | | nucleus | | A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent. |
