TATA-box binding protein associated factor (TAF) Inhibitors

TATA-box binding protein associated factors (TAFs) are a crucial group of proteins that form part of the transcription machinery, playing an integral role in the initiation of gene transcription. They are associated with TATA-binding protein (TBP) to form the TFIID complex, which recognizes and binds to the TATA box sequence within the promoter region of genes. This interaction facilitates the assembly of the pre-initiation complex and the recruitment of RNA polymerase II, leading to the initiation of transcription. TAFs contribute to gene expression regulation, influencing both basal and regulated transcription processes. They also have a pivotal role in various cellular processes such as cell cycle regulation, differentiation, and development.

TAF-specific inhibitors are designed to target the function or interactions of TAF proteins within the transcription complex. While specific small molecule inhibitors directly targeting TAFs might be limited, researchers have explored approaches that indirectly modulate TAF activity. Some strategies involve targeting downstream components of the transcription machinery, such as RNA polymerase II or transcriptional coactivators. Additionally, compounds that affect chromatin structure and epigenetic modifications, like histone deacetylase inhibitors or DNA methylation modifiers, can indirectly influence TAF-mediated transcription.
