ATG

Autophagy-related proteins (ATG) constitute a class of proteins essential for cellular autophagy, participating in the regulation of intracellular degradation and recycling processes. The ATG protein family comprises numerous members, including ATG1, ATG3, ATG4, ATG5, ATG7, and ATG8, each performing distinct roles during different stages of autophagosome formation, extension, and maturation. For instance, ATG7 functions as an E1-like enzyme responsible for activating ubiquitin-like proteins ATG12 and ATG8, while ATG5 serves as the binding partner for ATG12; both jointly contribute to autophagosome expansion. Abnormal expression or dysfunction of ATG proteins is closely associated with the onset and progression of various diseases, including neurodegenerative disorders, cardiovascular diseases, and cancer.

LC3B recruiter 2 (34R) is an LC3B recruiting agent incorporated into the autophagy-lysosome pathway degradation system (ATTEC, Autophagy-Tethering Compounds), with a direct binding affinity for LC3B. It connects via a linker to the CDK9 inhibitor SNS-032, creating an ATTEC capable of targeting and degrading the CDK9 and Cyclin T1 complex, while also inhibiting them. Consequently, LC3B recruiter 2 exerts its function through an LC3B-dependent autophagy-lysosome pathway, interfering with the cancer cell cycle progression, thereby demonstrating antitumor activity.
