| - | '''TGF-β receptors''' (Transforming Growth Factor) (TGFR) are serine/threonine kinase receptors. They are involved in paracrine signaling and are found in many types of tissue.

| + | *'''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 II''' is a tumor suppressor transmembrane protein. TGFR II has high affinity for TGF-β1 and low affinity for TGF-β2. <br /> | ||
| + | *'''TGFR III''' is a cell-surface chondroitin sulfate / heparin sulfate proteoglycan. It acts as a reservoir of ligand for TGFRs. TGFR III has high affinity for TGF-β1, TGF-β2 and TGF-β1.2. | ||
