TATA-box binding protein-associated factor 5 (TAF5) is a critical subunit of the TFIID complex, a multiprotein assembly essential for RNA polymerase II-mediated transcription initiation. As part of the transcription factor IID (TFIID), TAF5 plays a pivotal role in recognizing core promoter elements, recruiting coactivators, and stabilizing the interaction between TFIID and the TATA-box or other promoter regions. Structurally, TAF5 contains a conserved histone-fold domain that facilitates its interaction with other TAFs to form the core scaffold of the TFIID complex. Beyond its canonical role in transcription, TAF5 has been implicated in regulating cell cycle progression, differentiation, and apoptosis through interactions with diverse signaling pathways.
Recombinant human TAF5 protein, produced via heterologous expression systems like *E. coli* or mammalian cells, enables functional and structural studies. It is widely used to investigate TFIID assembly mechanisms, promoter-specific transcription regulation, and protein interaction networks. Researchers employ recombinant TAF5 in pull-down assays, chromatin immunoprecipitation (ChIP), and *in vitro* transcription reconstitution experiments. Notably, dysregulation of TAF5 has been associated with cancers and developmental disorders, making it a potential therapeutic target. Its recombinant form aids in screening for inhibitors or modulators targeting transcription-related pathologies. Studies also leverage tagged or truncated TAF5 variants to dissect domain-specific functions, enhancing our understanding of transcriptional dysregulation in disease contexts.
