Biochem/physiol Actions

A01 is a high affinity selective inhibitor of E3 ubiquitin-protein ligase Smurf1 (Smad ubiquitination regulatory factor-1) that disturbs Smurf1-Smad1/5 interaction and blocks Smurf1 mediated Smad1/5 ubiquitination. A01 increases responsiveness to BMP-2 in myoblasts and osteoblasts.

Diapause, an important strategy used by insects to avoid adverse environments, is regulated by various cell signaling pathways. The results of our previous studies demonstrated that the transforming growth factor-β (TGF-β) signaling pathway regulated pupal diapause in Helicoverpa armigera, which

Transforming growth factor (TGF)β1 has repeatedly been associated with axonal regeneration and recovery after injury to the CNS. We found TGFβ1 upregulated in the stroke-denervated mouse spinal cord after ischemic injury to the motor cortex as early as 4 d

TGF-β/BMP signaling pathway plays a significant role in fibrotic cataract. Smurf1, a ubiquitin protein ligase, regulates the TGF-β/BMP signaling pathway through the ubiquitin-proteasome system (UPS). This study aims to investigate the role of Smurf1 in the progression of fibrotic cataract
