Thymosin beta 4 is a 5kD member of the B-thymosin family of molecules.
Members of this family range from 41-44aa in length, and possess an isoelectric point that lies between pH 4.0-7.0 a-thymosins have values less than 4.0.
Multiple cell types produce TB4, either constitutively, or after stimulation.
They include platelets, endothelial cells, neutrophils, astrocytes and macrophages.
TB4 is both a secreted and intracellular molecule.
The secreted form contributes to wound healing and angiogenesis, and may act on ATPase.
Intracellularly, it forms a 1:1 complex with G-actin and blocks F-actin polymerization.
This regulates the availablility of actin monomers for filament formation and subsequent cell migration.
Mature human TB4 is 43aa in length aa2-44.
It contains an actin-binding site aa17-23, one acetylated Ser and five acetylated lysines (4; 12; 26; 32; 39) and one phosphorylation site at Thr23.
TB4 undergoes proteolytic processing to generate an N-terminal acetylated peptide aa2-5: SerAspLysPro.
Mature human TB4 is identical to mouse TB14 in aa sequence, and it shares 74% aa identity with its human family member TB10.
