Plays an important role in the organization of the cytoskeleton. Binds to and sequesters actin monomers (G actin) and therefore inhibits actin polymerization. Oncorhynchus mykiss (taxid: 8022)
>PF01290 Thymosin: Thymosin beta-4 family; InterPro: IPR001152 Thymosin beta-4 is a small polypeptide whose exact physiological role is not yet known []
It was first isolated as a thymic hormone that induces terminal deoxynucleotidyltransferase. It is found in high quantity in thymus and spleen but is widely distributed in many tissues. It has also been shown to bind to actin monomers and thus to inhibit actin polymerisation []. A number of peptides closely related to thymosin beta-4 belong to this family. They include, thymosin beta-9 (and beta-8) in Bos taurus (Bovine) and Sus scrofa (Pig), thymosin beta-10 in Homo sapiens (Human) and Rattus norvegicus (Rat), thymosin beta-11 and beta-12 in Oncorhynchus mykiss (Rainbow trout) and human Nb thymosin beta.; GO: 0003779 actin binding, 0007010 cytoskeleton organization, 0005737 cytoplasm; PDB: 1T44_G 1HJ0_A 3U9Z_C 3U9D_D 1SQK_B 3U8X_D 3SJH_B 2FF6_H.
