5-Ph-IAA is a bumped auxin-inducible degron (AID) ligand that induces Skp1-Cul1-F-box (SCF) E3 ligase complex-mediated ubiquitinaton of Arabidopsis IAA17-derived mini-AID (mAID) degron-fused target proteins in cells expressing a hole-modified Oryza sativa TIR1 (OsTIR1) mutant (F74G or F74A). Unlike the traditional AID system, 5-Ph-IAA-based AID2 method shows no detectable leaky degradation, requires a 670-times lower ligand concentration, and achieves quicker degradation in cultures (0.2-5 μM) and in vivo (1-10 mg/kg via daily i.p. to mice xenografted with HCT116 CMV-OsTIR1(F74G) cells expressing mAID-tagged BRD4 or TOP2A).

Targeted protein depletion using a conditional degron is a powerful method to probe the role of proteins in living cells because of the speed with which depletion can be induced and its reversibility. The auxin-inducible degron (AID) is one of
