dFKBP-1 is primarily utilized in biochemical research, particularly in the study of protein-protein interactions and cellular signaling pathways. It serves as a valuable tool in understanding the mechanisms of immunosuppression and the role of FKBP proteins in various biological processes. Researchers employ dFKBP-1 to investigate the effects of FKBP inhibition on cellular functions, which can provide insights into the development of therapeutic agents for conditions such as autoimmune diseases and cancer. Additionally, it is used in the design of chemical inducers of dimerization (CIDs), which are instrumental in controlling protein activity and studying gene expression in experimental models. Its application extends to the field of synthetic biology, where it aids in the construction of engineered systems for precise manipulation of cellular processes.
