PROTAC CBP/P300 Degrader-1 is a cereblon-recruiting degrader designed to remove the transcriptional coactivators CBP and p300, which contain druggable epigenetic reader and catalytic regulatory domains. Product sources describe it as a potent CBP/P300 degrader with activity in multiple cancer-cell-line models, while detailed public information on its exact CBP/P300 binding site is limited. In PROTAC design, the compound connects a CBP/P300-recognition ligand to a cereblon ligand via a linker, enabling induced proximity between the coactivator target and the CRL4-cereblon ubiquitin ligase complex. Its mechanism is expected to involve target recruitment, ubiquitination, and proteasomal degradation, thereby perturbing acetylation-dependent transcriptional programs. It is useful for epigenetic target validation, enhancer biology, transcriptional dependency studies, and optimization of degraders against large chromatin-associated proteins.

Target: Targets CBP and p300 bromodomain acetyltransferase paralogs for experimental targeted protein degradation studies.
Binding Site: Binds the CBP/p300 bromodomain acetyl-lysine pocket and cereblon ligand module to support productive ternary complex formation.
Mechanism of Action: PROTAC CBP/P300 Degrader-1 is designed for use in PROTAC or targeted protein degradation experiments directed toward CBP and p300 bromodomain acetyltransferase paralogs. The bifunctional molecule links a target-recognition element to cereblon, promoting proximity between the protein of interest and ubiquitination machinery. Productive ternary-complex formation can drive polyubiquitination and proteasome-dependent target depletion, allowing researchers to compare pharmacological inhibition with protein removal. It is suitable for evaluating degradation potency, kinetics, pathway selectivity, and downstream signaling consequences in engineered or disease-relevant cellular models.
