PROTAC CDK9 Degrader 1 is primarily used in research to target and degrade cyclin-dependent kinase 9 (CDK9) within cells. This chemical is particularly valuable in studying the role of CDK9 in transcriptional regulation and its involvement in diseases such as cancer. By degrading CDK9, researchers can investigate the downstream effects on gene expression, cell cycle progression, and apoptosis. This tool is also utilized to explore potential therapeutic strategies for cancers where CDK9 activity is dysregulated, offering insights into the development of targeted treatments. Additionally, it aids in understanding the broader mechanisms of protein degradation pathways, contributing to advancements in the field of targeted protein degradation.
