Transforming growth factor-beta (TGF-beta) superfamily members are critical regulators of cell proliferation and differentiation, developmental patterning and morphogenesis, and disease pathogenesis (1-4).
TGF-beta elicits signaling through three cell surface receptors: type I (RI), type II (RII), and type III (RIII).
Type I and type II receptors are serine/threonine kinases that form a heteromeric complex.
In response to ligand binding, the type II receptors form a stable complex with the type I receptors allowing phosphorylation and activation of type I receptor kinases (5).
The type III receptor, also known as betaglycan, is a transmembrane proteoglycan with a large extracellular domain that binds TGF-beta with high affinity but lacks a cytoplasmic signaling domain (6,7).
Expression of the type III receptor can regulate TGF-beta signaling through presentation of the ligand to the signaling complex.
The only known direct TGF-beta signaling effectors are the Smad family proteins, which transduce signals from the cell surface directly to the nucleus to regulate target gene transcription (8,9).
Three isoforms of TGF-beta, designated TGF-beta1, TGF-beta2 and TGF-beta3, are encoded by distinct genes and are expressed in a tissue specific manner (10).
Each isoform is synthesized as a larger precursor protein containing a propeptide region that is removed prior to secretion.
Mature TGF-beta contains two polypeptides linked by disulfide bonds to form a protein of approximately 25kD.
