The three mammalian isoforms of TGF-beta, TGF-beta1, beta2, beta3, signal through the same receptor and elicit similar biological responses. They are multifunctional cytokines that regulate cell proliferation, growth, differentiation and motility as well as synthesis and deposition of the extracellular matrix. They are involved in various physiological processes including embryogenesis, tissue remodeling and wound healing. They are secreted predominantly as latent complexes which are stored at the cell surface and in the extracellular matrix. The release of biologically active TGF-beta isoform from a latent complex involves proteolytic processing of the complex and /or induction of conformational changes by proteins such as thrombospondin-1. The physiological role of TGF-beta3 is still unknown but its expression pattern suggests a role in the regulation of certain development processes. Recombinant human TGF-beta3 is a 25kD protein composed of two identical 112aa polypeptide chains linked by a single disulfide bond.
