Furan warheads for covalent trapping of weak protein-protein interactions : cross-linking of thymosin β4 to actin

We describe furan as a triggerable 'warhead' for site-specific cross-linking using the actin and thymosin beta 4 (T beta 4)-complex as model of a weak and dynamic protein-protein interaction (PPI) with known 3D structure and with application potential in disease contexts. The identified cross-linked residues demonstrate that lysine is a target for the furan warhead. The presented in vitro validation of covalently acting 'furan-armed' T beta 4-variants provides initial proof to further exploit furan-technology for covalent drug design targeting lysines.
