Transforming growth factor beta-3 is a protein that in humans is encoded by the TGFB3 gene. [ 5 ] [ 6 ] It is a type of protein, known as a cytokine , which is involved in cell differentiation , embryogenesis and development .
Transforming growth factor beta (TGF-β) is a multifunctional cytokine belonging to the transforming growth factor superfamily that includes three [1] different mammalian isoforms (TGF-β 1 to 3, HGNC symbols TGFB1, TGFB2, TGFB3) and many other signaling proteins. TGFB proteins are produced by all white blood cell lineages.
They interact with TGF-beta receptors. Many proteins have since been described as members of the TGF-β superfamily in a variety of species, including invertebrates as well as vertebrates and categorized into 23 distinct gene types that fall into four major subfamilies: [3] [4] [5] The TGF-β subfamily
All three TGFβ1, TGFβ2 and TGFβ3. are synthesized as precursor molecules containing a propeptide region in addition to the TGF-β homodimer. [10] After it is synthesized, the TGF-β homodimer interact with a Latency Associated Peptide (LAP)[a protein derived from the N-terminal region of the TGF beta gene product] forming a complex called Small Latent Complex (SLC).
TGFBR3 is composed of an extracellular receptor domain consisting of 849 amino acids which is intracellularly connected to a short cytoplasmic domain. Betaglycan, being expressed by a whole range of various cell types within the organism, can be found in the form of a membrane-bound receptor, or as a soluble protein capable of interactions with the extracellular matrix ().
The TGF beta ligand binds to a type II receptor dimer, which recruits a type I receptor dimer forming a hetero-tetrameric complex with the ligand. [6] These receptors are serine/threonine kinase receptors. They have a cysteine rich extracellular domain, a transmembrane domain, and a cytoplasmic serine/threonine rich domain.

Transforming growth factor ([attribution needed], or TGF) is used to describe two classes of polypeptide growth factors, TGFα and TGFβ. The name "Transforming Growth Factor" is somewhat arbitrary, since the two classes of TGFs are not structurally or genetically related to one another, and they act through different receptor mechanisms .
