Protein description
|
Thymosin is a hormone secreted from the thymus. The predominant form of thymosin, thymosin b4, is a member of a highly conserved family of actin monomer sequestering proteins. Beta-thymosins are the primary regulators of unpolymerized actin, and are essential for maintaining the small cytoplasmic pool of free G-actin monomers required for rapid filament elongation and allowing for the flux of monomers between the thymosin bound pool and F-actin.
