The proteins thymosin and profilin prevent the spontaneous nucleation of new actin trimers. The growth of actin filaments can be regulated by thymosin and profilin. Other proceedings are active before Australian courts regarding Dank's supply of thymosin beta on sportsmen. Thymosin beta-4 was allegedly used by some players in various Australian football codes. Taken together, these effects suggest that thymosin has a general role in tissue regeneration. Thymosin beta-4 is a protein that in humans is encoded by the "TMSB4X" gene. Thymosin beta-10 is a protein that in humans is encoded by the "TMSB10" gene.
