TACE-mediated ectodomain shedding of the type I TGF-beta receptor downregulates TGF-beta signaling.
Regulating TGF-beta receptor presentation provides an avenue to alter a cell's responsiveness to TGF-beta. We report that activation of the Erk MAP kinase pathway decreases the TGF-beta-induced Smad3 activation due to decreased cell surface levels of the type I receptor TbetaRI, but not the type II receptor. Inhibition of TACE activity or expression enhanced the cell surface TbetaRI levels and ...
متن کاملTβRIII independently binds type I and type II TGF-β receptors to inhibit TGF-β signaling
Transforming growth factor-β (TGF-β) receptor oligomerization has important roles in signaling. Complex formation among type I and type II (TβRI and TβRII) TGF-β receptors is well characterized and is essential for signal transduction. However, studies on their interactions with the type III TGF-β coreceptor (TβRIII) in live cells and their effects on TGF-β signaling are lacking. Here we invest...

TGF-beta induced transdifferentiation of mammary epithelial cells to mesenchymal cells: involvement of type I receptors
The secreted polypeptide transforming growth factor-beta (TGF-beta) exerts its multiple activities through type I and II cell surface receptors. In epithelial cells, activation of the TGF-beta signal transduction pathways leads to inhibition of cell proliferation and an increase in extracellular matrix production. TGF-beta is widely expressed during development and its biological activity has b...
متن کاملThe immunophilin FKBP12: a molecular guardian of the TGF-beta family type I receptors.
FKBP12 as an immunophilin that binds to two well-known immunosuppressive macrolides, FK506 and rapamycin, has attracted immense attention and its role in mediating the immunosuppressive functions of these macrolides has been extensively studied. Since FKBP12 is a well-conserved protein among many species and is also highly expressed in almost all cells, it must play important roles in cellular ...
