PROTAC AR Degrader-4 comprises a IAP ligand binding group, a linker and an Androgen Receptor (AR) binding group. PROTAC AR Degrader-4 is an AR degrader. Degradation inducers based on cIAP1 are called specific and non-genetic IAP-dependent protein erasers (SNIPERs).In Vitro: Specific and Nongenetic IAPs-dependent Protein Erasers (SNIPERs) are bifunctional compounds which are designed by conjugating an IAPs-recognition structure with a target protein-recognition structure.
Targeting proteins for degradation involves three steps.
1, its two recognition structures allow SNIPER to form a complex linking IAPs, which have E3 ligase activity, with the target protein.
2, the target protein is polyubiquitinated by IAPs.
3, the polyubiquitinated protein is degraded by proteasome.
