Encyclopedia: Thymosin
Thymosin is an actin-binding protein in cells. The predominant form of thymosin, thymosin 4, is a member of a highly conserved family of actin monomer-sequestering proteins. -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 . Thymosin 4 sequesters actin,...
