About TB Fragment (Thymosin β4 17–23)
Thymosin β4 binds G-actin through a central motif, LKKTETQ, spanning residues 17–23. Synthetic peptides built around this motif, most often the N-acetylated heptapeptide Ac-LKKTETQ, are used when researchers want the actin-binding region without the full 43-amino-acid peptide.
