TGF-β signaling regulates diverse cellular processes, including cell proliferation, differentiation, apoptosis, cell plasticity and migration. Its dysfunctions can result in various kinds of diseases, such as cancer and tissue fibrosis. TGF-β signaling is tightly regulated at different levels along the pathway, and modulation of TGF-β receptor activity is a critical step for signaling regulation. This review focuses on our recent understanding of regulation of TGF-β receptor activity.
