findings demonstrate TGF-beta enhances expression of USP26 and reinforces SMAD7 stability by limiting the ubiquitin-mediated turnover of SMAD7; clinically, loss of USP26 correlates with high TGF-beta activity and confers poor prognosis in glioblastoma; data identify USP26 as a novel negative regulator of the TGF-beta pathway and suggest that loss of USP26 expression may be an important factor in glioblastoma pathogenesis

Smad7 inhibition diminishes interaction of PKR with protein kinase inhibitor p58 (p58(IPK)).
We confirmed that Smad7 was a direct target of miR-21. miR-21 knockout resulted in increased expression of Smad7 and impaired phosphorylation of the Smad2/3 complex
Eplerenone inhibited atrial fibrosis in MHC-TGFcys33ser transgenic mice. The underlying mechanism may involve increased protein expression of Smad7, which enhances the inhibitory feedback regulation of TGF-beta1/Smad signaling.

Results suggest that myostatin auto-regulates its gene expression through a Smad7 dependent mechanism in myogenic cells.
The protein encoded by this gene is a nuclear protein that binds the E3 ubiquitin ligase SMURF2. Upon binding, this complex translocates to the cytoplasm, where it interacts with TGF-beta receptor type-1 (TGFBR1), leading to the degradation of both the encoded protein and TGFBR1. Expression of this gene is induced by TGFBR1. Variations in this gene are a cause of susceptibility to colorectal cancer type 3 (CRCS3). Several transcript variants encoding different isoforms have been found for this gene.
