TB500

TB-500 is a synthetic peptide corresponding to the N-acetylated LKKTETQ sequence, a functional region of the naturally occurring protein thymosin β4. This seven-amino acid fragment represents the actin-binding domain of thymosin β4, which has been associated with cellular processes such as actin regulation, cell migration, and tissue remodelling. Developed as a research compound, TB-500 is used in laboratory investigations exploring the biological functions of the thymosin β4 actin-binding motif and its role in cellular signalling.
