DUBs inhibitor 2 is primarily used in biochemical research to study the role of deubiquitinating enzymes (DUBs) in cellular processes. It is particularly valuable in investigating protein degradation pathways, ubiquitin signaling, and the regulation of protein stability. Researchers utilize this inhibitor to explore its effects on cancer cells, as DUBs are often implicated in tumor growth and survival. Additionally, it aids in understanding immune responses and neurodegenerative diseases, where DUBs play a critical role. Its application extends to drug discovery, where it serves as a tool for identifying potential therapeutic targets by modulating DUB activity.
