*'''TGFR I''' forms heteromeric complex with TGFR II when it is bound to TGF-β. The complex transduces the TGF-β signal from the cell surface to the cytoplasm by phosphorylating proteins which regulate the transcription of genes related to cell proliferation. TGFR I has high affinity for TGF-β1 and low affinity for TGF-β2. <br />

TGFR structure contains a 100-140 residues ligand-binding N-terminal extracellular domain; a transmembrane domain; a 350-400 amino acid cytoplasmic kinase domain; and a C-terminal zona pellucida (ZP) domain of ca 260 residues which has a role in protein polymerization.
