Mechanism
Mechanism in research
Thymosin beta-4 is described in the literature as the main protein that binds free actin molecules (G-actin) in the cell. It therefore plays a role in building the cytoskeleton and in cell migration. TB-500 is based on the actin-binding region of this protein.
Research
What is TB-500 studied for?
- Research into cell migration
- Research into angiogenesis
