Preferred Names: histone acetyltransferase TRA1

NP_011967.1

Subunit of SAGA and NuA4 histone acetyltransferase complexes; subunit of the TTT Hsp90 cochaperone complex that is involved in chromatin remodeling and telomeric chromatin regulation; interacts with acidic activators (e.g., Gal4p) which leads to transcription activation; similar to human TRRAP, which is a cofactor for c-Myc mediated oncogenic transformation
