Thymosin β4 is an actin-sequestering peptide that modulates inflammation and healing in different tissues. It plays a major role in angiogenesis and tumor metastasis. Thymosin beta4 (Tβ4) is an extensively conserved protein known for its diverse biological functions. As a member of the thymosin protein family, Thymosin β4 plays a role in regulating the immune system, cell growth, and tissue healing. It is present in all vertebrates and is highly expressed in both embryonic and adult tissues. Tβ4 serves as a versatile protein that exhibits anti-inflammatory, antioxidant, and wound healing properties. It is actively involved in cell migration, tissue regeneration, and interacts with various proteins, such as growth factors, cytokines, and receptors. Through these interactions, Tβ4 modulates the activities of these proteins, influencing the cell′s response to different stimuli. Its effects encompass a wide range of biochemical and physiological processes, including the regulation of enzyme activity, gene expression, and signal transduction pathways. Additionally, Tβ4 impacts cell proliferation, migration, and differentiation, contributing to the overall complexity of its biological effects.
