AAS104, ADA4, SWI9, histone acetyltransferase GCN5, KAT2, L000000684, YGR252W

Catalytic subunit of ADA and SAGA histone acetyltransferase complexes; modifies N-terminal lysines on histones H2B and H3; acetylates Rsc4p, a subunit of the RSC chromatin-remodeling complex, altering replication stress tolerance; relocalizes to the cytosol in response to hypoxia; mutant displays reduced transcription elongation in the G-less-based run-on (GLRO) assay; greater involvement in repression of RNAPII-dependent transcription than in activation

Affinity Capture-Western

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner identified by Western blot with a specific polyclonal antibody or second epitope tag. This category is also used if an interacting protein is visualized directly by dye stain or radioactivity. Note that this differs from any co-purification experiment involving affinity capture in that the co-purification experiment involves at least one extra purification step to get rid of potential contaminating proteins.

The Gcn5 bromodomain of the SAGA complex facilitates cooperative and cross-tail acetylation of nucleosomes.

Li S, Shogren-Knaak MA

Bromodomains are acetyl lysine binding modules found in many complexes that regulate gene transcription. In budding yeast, the coactivator complex SAGA (Spt-Ada-Gcn5-acetyl-transferase) predominantly facilitates transcription of stress-activated genes and requires the bromodomain of the Gcn5 subunit for full activation of a number of these genes. This bromodomain has previously been shown to promote retention of the complex to H3 and ... [more]
