The Dossier
Research Notes
TB-500 is a synthetic, N-acetylated heptapeptide corresponding to the actin-binding domain (residues 17–23) of Thymosin Beta-4, a ubiquitous actin-regulating protein of the β-thymosin family. It retains the LKKTETQ motif that defines the parent molecule's interaction with the cytoskeleton.
It is a familiar reference within the recovery category, studied for its role in cell motility and tissue organization, and frequently examined alongside complementary repair-signaling peptides.
Research Focus
- Dermal, corneal, and aged-wound repair models
- Musculoskeletal (muscle, tendon, ligament) recovery
- Cardiovascular and angiogenesis models
- Neuroprotection and CNS-repair models
- Actin sequestration and cytoskeletal biology
Mechanism
The LKKTETQ motif binds monomeric globular actin in a one-to-one complex, regulating actin polymerization and cytoskeletal organization — the basis of its documented influence on cell migration.
Research has additionally characterized interactions that engage Akt survival signaling, modulate NF-κB inflammatory signaling, and upregulate matrix metalloproteinases associated with tissue remodeling.
