Inducible expression and protein degradation systems switch a gene or a protein on or off with a small molecule. In tetracycline-controlled (Tet-On) systems, doxycycline activates transcription of the target gene. 4-Hydroxytamoxifen activates Cre recombinase fused to a modified estrogen receptor (CreER), and isopropyl β-D-1-thiogalactopyranoside (IPTG) induces lac-controlled genes in bacteria. Chemical inducers of dimerization such as AP20187 and abscisic acid bring fusion proteins together on demand. Degron systems remove tagged proteins within hours, with dTAG-13 for FKBP12 F36V fusions and 5-Ph-IAA for the auxin-inducible degron 2 (AID2) system. Shield-1 offers a further switch, as it stabilizes proteins fused to a destabilizing domain.
