PROTAC ERRα Degrader-2 is primarily used in research settings to target and degrade the estrogen-related receptor alpha (ERRα) protein. This chemical is a key tool in studying the role of ERRα in various biological processes, particularly in cancer research, where ERRα is often overexpressed and linked to tumor growth and progression. By degrading ERRα, researchers can investigate its impact on cellular functions and explore potential therapeutic strategies for ERRα-driven cancers. Additionally, it aids in understanding the broader mechanisms of targeted protein degradation, contributing to advancements in the development of PROTAC-based therapies.
