TRA1

histone acetyltransferase TRA1, L000003945, YHR099W
Subunit of SAGA and NuA4 histone acetyltransferase complexes; 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

Phenotypic Suppression

A genetic interaction is inferred when mutation or over expression of one gene results in suppression of any phenotype (other than lethality/growth defect) associated with mutation or over expression of another gene.

Tra1 is a 3744-residue component of the Saccharomyces cerevisiae SAGA, NuA4 and ASTRA complexes. Tra1 contains essential C-terminal PI3K and FATC domains, but unlike other PIKK (phosphoinositide three-kinase-related kinase) family members, lacks kinase activity. To analyze functions of the FATC domain we selected for suppressors of tra1-F3744A, an allele that results in slow growth under numerous conditions of stress. Two ... [more]
