KT-333

E3 Ligase: KT-333 recruits the cereblon (CRBN) E3 ligase, facilitating selective ubiquitination of target proteins. This recruitment stabilizes the ternary complex required for degradation.

Target Protein: KT-333 primarily targets STAT3, a transcription factor involved in inflammatory signaling. Engagement leads to disruption of STAT3-dependent transcriptional programs.

Degradation Mechanism: KT-333 mediates proteasomal degradation via the ubiquitin–proteasome system. Formation of the CRBN–STAT3 ternary complex promotes polyubiquitination and recognition by the 26S proteasome, resulting in efficient protein depletion.
