Succinimidyl 4-hydrazidoterephthalate hydrochloride

E3 Ligase: Succinimidyl 4-hydrazidoterephthalate hydrochloride does not directly recruit classical E3 ligases such as CRBN, VHL, IAP, or MDM2. It functions as a photoactivatable crosslinker that covalently labels proteins, which may indirectly influence the spatial proximity or availability of proteins to E3 ligases in experimental systems.

Target Protein: The compound targets primary amine residues on proteins through its N-hydroxysuccinimide ester and forms covalent bonds upon UV activation via its hydrazide group. By crosslinking proteins, it can stabilize transient interactions or bring proteins into proximity with E3 ligases, potentially modulating substrate ubiquitination indirectly.

Degradation Mechanism: Any impact on protein turnover occurs indirectly through the ubiquitin-proteasome system. Proteins crosslinked by Succinimidyl 4-hydrazidoterephthalate hydrochloride may be recognized and degraded by cellular machinery due to altered interaction networks, without direct engagement of lysosomal pathways.

• Molecular Glue Mechanism Exploration: Succinimidyl 4-hydrazidoterephthalate hydrochloride serves as a pivotal tool in studying the molecular glue mechanism, facilitating the stabilization of protein-protein interactions.
