The full 43-amino-acid peptide Thymosin beta-4 (Tbeta4, CAS 77591-33-4), a ubiquitous G-actin-sequestering protein present in nearly all human cells. The central actin-binding motif (residues 17-23, LKKTETQ) drives cytoskeletal dynamics, cell motility, and angiogenesis. Evaluated in Phase 2 for venous stasis ulcers, epidermolysis bullosa, and dry-eye disease; studied preclinically for myocardial and soft-tissue repair. Commonly marketed as "TB-500" by research-peptide vendors; not FDA-approved.
