Thymosin beta 4 Antibody [Unconjugated]

Thymosin beta 4 (T beta 4; also TB4X and Fx) is a 5.0 kDa member of the beta -thymosin family of molecules. Members of this family range from 41-44 amino acids (aa) in length, and possess an isoelectric point that lies between pH 4.0-7.0 ( alpha -thymosins have values less than 4.0). Multiple cell types produce T beta 4, either constitutively, or after stimulation. They include platelets, endothelial cells, neutrophils, astrocytes and macrophages. T beta 4 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 T beta 4 is 43 aa in length (aa 2-44). It contains an actin-binding site (aa 17-23), one acetylated Ser and five acetylated lysines (4; 12; 26; 32; 39) and one phosphorylation site at Thr23. T beta 4 undergoes proteolytic processing to generate an N-terminal acetylated peptide (aa 2-5: SerAspLysPro). Mature human T beta 4 is identical to mouse T beta 14 in aa sequence, and it shares 74% aa identity with its human family member T beta 10.
