dTAG-7 is primarily used in targeted protein degradation studies, particularly in the field of chemical biology and drug discovery. It functions as a bifunctional molecule that links a target protein to an E3 ubiquitin ligase, facilitating the ubiquitination and subsequent degradation of the protein via the proteasome. This approach, known as targeted protein degradation, allows researchers to study the effects of removing specific proteins from cells, providing insights into their biological roles and potential as therapeutic targets. dTAG-7 is especially valuable in validating drug targets, understanding protein function, and developing novel therapeutic strategies for diseases such as cancer, neurodegenerative disorders, and infectious diseases. Its precision in degrading proteins of interest makes it a powerful tool in both basic research and translational applications.
