As the dominant G-actin sequestering protein in mammalian cells, TB-500 binds globular actin with high affinity (Kd ~0.5 M) through a sophisticated triple-contact mechanism involving Lys-3, Lys-18, and Lys-38 residues, preventing spontaneous actin polymerization while maintaining a readily mobilizable reservoir for rapid cytoskeletal reorganization
