**Background of AATF Recombinant Protein**
AATF (Apoptosis Antagonizing Transcription Factor), also known as CHE-1 or DED, is a multifunctional protein implicated in critical cellular processes, including apoptosis regulation, cell cycle control, DNA damage response, and transcriptional regulation. Initially identified as an interactor of the HIV-1 Tat protein, AATF has since been recognized for its role in antagonizing p53-mediated apoptosis, promoting cell survival under stress conditions. Structurally, AATF contains conserved domains such as a proline-rich region, leucine zippers, and nuclear localization signals, facilitating its interactions with key signaling molecules like pRb, MYC, and PARP-1.
Recombinant AATF protein is engineered using heterologous expression systems (e.g., *E. coli* or mammalian cells) to produce purified, functional protein for research and therapeutic exploration. Its recombinant form enables detailed *in vitro* studies to dissect molecular mechanisms, including its role in modulating transcription via RNA polymerase II or its involvement in ribosome biogenesis. AATF’s dysregulation is linked to cancers, neurodegenerative diseases, and cardiovascular disorders, making it a potential biomarker or therapeutic target. For instance, its anti-apoptotic activity in tumor cells highlights its relevance in oncology, while its neuroprotective effects in models of Parkinson’s disease suggest broader therapeutic applications.
Current research focuses on elucidating AATF’s complex interactome and context-dependent functions. Challenges include understanding its dual roles in promoting survival versus inducing senescence and resolving structural details to guide drug design. Recombinant AATF remains a vital tool for uncovering its pathophysiological contributions and developing targeted therapies.
