Abstract:
AS1411-NCL-MDM2-based proteolysis-targeting chimeras (ANM-PROTACs) are capable of inducing selective degradation of transcription factors (TFs) in tumor cells. Here, we present a protocol for constructing ANM-PROTACs. We describe steps for molecular design of the ANM-PROTACs, assembly and characterization of the ANM-PROTACs, and initial assessment of in vitro TF degradation potency. We then detail procedures for validation of selective degradation of TFs via proteomic analysis. This protocol has been successfully applied to degrade various TFs across multiple tumor cell lines. For complete details on the use and execution of this protocol, please refer to Fu et al.1.
