Description

General description

TGF-β3 (transforming growth factor-β3) belongs to the TGF β superfamily. The TGFβ3 gene is mapped to human chromosome 14q24.3

Biochem/physiol Actions

TGF-β3 (transforming growth factor-β3) regulates lymphocyte proliferation, apoptosis, hematopoiesis and embryogenesis to maintain immune homeostasis. TGF-β plays an important role in cell growth, differentiation, and survival. TGF-β3 specifically promotes chondrogenic differentiation.TGF-β3 is a strong growth inhibitor for normal and transformed epithelial, lymphoid, fibroblast, and keratinocyte cells. TGF-2 inhibits antitumor action of NK (natural killer) cells, T-cells, macrophages, monocytes and neutrophils. TGF-β3 is a tumor suppressor in the early stages of carcinogenesis, but in the later stages acts as a tumor promoter by inducing epithelial-mesenchymal transition and stimulating angiogenesis. TGF-β isoforms is known to participate in wound healing and tissue fibrosis. TGF-β3 is crucial for tissue restoration and scarless tissue repair. Mutation in the TGFβ3 gene is associated with development of non-syndromic cleft palate only (NS CPO), a rare congenital disease.

TGF-β3 is less prevalent in natural expression than either TGF-β1 or TGF-β2, but it is the most abundant mRNA expressed in chick embryos. It is also expressed in human umbilical cord, in a variety of mesenchymal cells of human and rodent origin, and in several human carcinoma cells.

Physical form

Lyophilized from a 0.2 μm filtered solution of 50 mM NaOAc pH 4.5

Preparation Note

HumanKine TGF-β3 is expressed in human HEK 293 cells as a mature, disulfide linked, non- glycosylated homodimer with a predicted molecular mass of 25 kDa.
This product is lyophilized from a solution of 50mM NaOAc, pH 3.7.

Analysis Note

The specific activity was determined by the dose-dependent inhibition of IL-4 induced proliferation of mouse HT-2 cells (BALB/c spleen activated by sheep erythrocytes in the presence of IL-2).
