Biochem/physiol Actions
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).

Protein knockdown using the auxin-inducible degron (AID) technology is useful to study protein function in living cells because it induces rapid depletion, which makes it possible to observe an immediate phenotype. However, the current AID system has two major drawbacks:
