What is TGFBR1 protein?

TGFBR1 (transforming growth factor beta receptor 1) gene is a protein coding gene which situated on the long arm of chromosome 9 at locus 9q22. TGFβR1 or transforming growth factor, beta-receptor 1 is a member of the TGFβ receptor subfamily and is a ser/thr protein kinase that forms a heteromeric complex with type II TGF-beta receptors when bound to TGF-beta, transducing the TGF-beta signal from the cell surface to the cytoplasm. The TGFBR1 protein is consisted of 503 amino acids and its molecular mass is approximately 56.0 kDa.

What is the function of TGFBR1 protein?

TGFBR1 is a membrane bound serine/threonine kinase receptor. Its main function is to act as a receptor for transforming members of the growth factor-β (TGF-β) superfamily, mediating the transfer of TGF-β signals from the extracellular to the intracellular. TGF-β signaling pathway plays a key role in regulating cell proliferation, differentiation, migration, apoptosis and extracellular matrix synthesis. Normal function of TGFBR1 is essential for maintaining tissue homeostasis.

TGFBR1 Related Signaling Pathway

The TGF-β signaling pathway is the most important signaling pathway. In this pathway, TGF-β ligands first bind to TGF-β type II receptors, leading to phosphorylation of type I receptors such as TGFBR1. Phosphorylated type I receptors in turn activate SMAD proteins, which enter the nucleus and regulate gene expression. This pathway interacts with many other signaling pathways (cross-talk). For example, it interacts with pathways such as WNT, Hippo, Notch, IFN, TNF, and RAS, and this interaction can affect a variety of biological processes such as cell proliferation, differentiation, and apoptosis.

TGFBR1 Related Diseases

Normal function of TGFBR1 is essential for maintaining tissue homeostasis and inhibiting tumorigenesis, but its dysfunction has been associated with a variety of diseases, including cancer, pulmonary fibrosis, and certain genetic disorders such as Loeys-Dietz syndrome and hereditary hemorrhagic telangiectasia (HHT). In addition, there are atherosclerosis, liver cirrhosis, diabetic nephropathy and so on.

Bioapplications of TGFBR1

As a potential drug target, TGFBR1 research may drive the development of new therapeutic strategies. For example, research targeting dual inhibitors of TGF-β/PD-L1 may provide new avenues for tumor treatment.

Case study 1: David A Monteiro, 2021

Bone is a dynamic tissue that constantly adapts to changing mechanical demands. The transforming growth factor beta (TGFβ) signaling pathway plays several important roles in maintaining skeletal homeostasis by both coupling the bone-forming and bone-resorbing activities of osteoblasts and osteoclasts and by playing a causal role in the anabolic response of bone to applied loads. However, the extent to which the TGFβ signaling pathway in osteocytes is directly regulated by fluid shear stress (FSS) is unknown.

To investigate the effects of FSS on TGFβ signaling in osteocytes, the researchers stimulated osteocytic OCY454 cells cultured within a microfluidic platform with FSS. Relative to treatment with TGFβ, FSS induced a larger increase in levels of pSmad2/3 and Serpine1 that persisted even in the presence of a TGFβ receptor type I inhibitor. The results show that FSS stimulation rapidly induces phosphorylation of multiple TGFβ family R-Smads by stimulating multimerization and concurrently activating several TGFβ and BMP type I receptors, in a manner that requires the activity of the corresponding ligand.

Case study 2: Seong Ji Park, 2016

Transforming growth factor-β1 (TGF-β1) promotes tumor metastasis by inducing an epithelial-to-mesenchymal transition (EMT) in cancer cells. In this study, the researchers investigated the effects of BIX02189 and XMD8-92, pharmacologic inhibitors of the MEK5 [mitogen-activated protein kinase/extracellular-signal-regulated kinase (ERK)5] signaling pathway, on the EMT and migration of cancer cells induced by TGF-β1. In human A549 lung cancer cells, TGF-β1-induced EMT, cell motility, and expression of matrix metalloproteinase-2 were completely inhibited by BIX02189, but not by XMD8-92 or small interference RNAs specific to MEK5 and ERK5. Molecular docking simulation and kinase assays revealed that BIX02189 binds directly to the ATP-binding site of the TGF-β receptor type I (TβRI) and suppresses its kinase activity. Finally, the anti-metastatic effect of BIX02189 was validated in a TβRI-derived A549 xenograft mouse model.


Fig3. A549 cells were pretreated with BIX02189 (upper panel) or XMD8-92 (lower panel) at the indicated concentrations for 30 min and then stimulated with TGF-β1 (5 ng/ml) for 36 h in serum-free medium.
