Targeted protein degradation (TPD) strategies exploit bivalent small molecules to bridge substrate proteins to an E3 ubiquitin ligase to induce substrate degradation. Few E3s have been explored as degradation effectors due to a dearth of E3-binding small molecules. We show that genetically induced recruitment to the GID4 subunit of the CTLH E3 complex induces protein degradation. An NMR-based .... Mean H3 (during 40 s after MB arrival) showed a positive correlation ( r2 = 0.76) with Ktrans. Two different target levels, low H3 (26 dB) and high H3 (30 dB), were selected from training data to represent different MB dynamics regime (weak-stable and strong-stable cavitation, see Methods for details).
