Sequence: Ac-Leu-Lys-Lys-Thr-Glu-Thr-Gln (Active Fragment)
Format: Actin-Sequestering Peptide
Chemical Description
TB-500 is a synthetic N-acetylated heptapeptide that replicates the actin-binding region of Thymosin Beta-4. Biochemically, it functions as an actin-sequestering molecule, maintaining a pool of monomeric G-actin in the cytoplasm. This interaction is critical for the rapid polymerization of actin filaments (F-actin) required for cytoskeletal reorganization. Research focuses on its role in facilitating cell motility and tissue morphogenesis markers in culture models.
Research Applications
This compound is strictly for laboratory research use in the study of:
