behind the compound.
Overview
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.
