**Background of TADA3 Recombinant Protein**
TADA3 (Transcriptional Adaptor 3), also known as ADA3. is a conserved component of histone acetyltransferase (HAT) complexes, including the PCAF and GCN5-containing complexes, which are critical for chromatin remodeling and transcriptional regulation. It plays a pivotal role in modifying chromatin structure by facilitating histone acetylation, thereby promoting gene activation. TADA3 is essential for cell cycle progression, DNA damage response, and apoptosis, largely through its interaction with p53. By stabilizing p53 and enhancing its transcriptional activity, TADA3 contributes to the regulation of genes involved in tumor suppression and stress responses. Dysregulation of TADA3 has been implicated in cancers, developmental disorders, and other diseases linked to epigenetic and transcriptional dysfunction.
Recombinant TADA3 protein is engineered using expression systems (e.g., *E. coli*, mammalian cells) to produce a purified, functional form of the protein for research applications. It typically retains post-translational modifications when expressed in eukaryotic systems, ensuring biological relevance. Researchers utilize TADA3 recombinant protein to study its interactions with HAT complexes, p53. and other partners, as well as to investigate its enzymatic activity in acetylation assays. It also serves as a tool for exploring mechanisms of epigenetic regulation, cancer biology, and potential therapeutic targeting. Additionally, it aids in structural studies (e.g., crystallography) and high-throughput drug screening to identify modulators of TADA3-associated pathways.
Overall, TADA3 recombinant protein is a valuable resource for unraveling the molecular basis of transcriptional regulation and developing strategies to address diseases tied to epigenetic dysregulation.
