Bdf1 Activators

Bdf1, or Bromodomain Factor 1, is a protein found in yeast, specifically Saccharomyces cerevisiae. The protein is characterized by the presence of bromodomains, protein motifs that recognize and bind to acetylated lysine residues on histone proteins, thereby influencing chromatin structure and gene expression.Bdf1 is a subunit of the SWR1 complex, a chromatin-remodeling complex that is involved in the replacement of histone H2A with the H2A.Z variant. This histone replacement plays a critical role in controlling gene expression, chromosome segregation, and DNA repair.

Bdf1 is also a component of the TFIID complex, a general transcription factor required for the initiation of transcription by RNA polymerase II. In this context, Bdf1 helps facilitate the binding of the TFIID complex to promoter regions of genes, thereby influencing their transcription.Through its involvement in these processes, Bdf1 plays a critical role in regulating gene expression in yeast. It contributes to various cellular functions, including cell cycle progression, response to stress, and maintenance of genome stability.While Bdf1 is specific to yeast, it has homologs in higher eukaryotes, including humans, where similar bromodomain-containing proteins play vital roles in gene regulation. Dysregulation of these proteins can contribute to disease states, including cancer.
