Biochim Biophys Acta 1759:503-13. 2006..With recent advance in the knowledge of regulatory factors impinged on Smads, we are beginning to understand the complexity in cellular responses to TGF-beta...
Specific nucleoporin requirement for Smad nuclear translocationXiaochu Chen
Program in Molecular Medicine, University of Massachusetts Medical School, 373 Plantation Street, Worcester, MA 01605, USA
Mol Cell Biol 30:4022-34. 2010..Thus, we have delineated the nucleoporin requirement of MAD nuclear import, reflecting a unique trans-NPC mechanism...
Nucleocytoplasmic shuttling of signal transducersLan Xu
Program in Molecular Medicine, University of Massachusetts Medical School, Worcester, Massachusetts 01605, USA

Smad inhibition by the Ste20 kinase MisshapenSatoshi Kaneko
Program in Molecular Medicine and Department of Cancer Biology, University of Massachusetts Medical School, Worcester, MA 01605, USA
Proc Natl Acad Sci U S A 108:11127-32. 2011..Our findings thus reveal a function of Msn independent of its impact on MAP kinase cascades. This Smad inhibition mechanism by Msn likely has important implications for development and disease...
Preferential utilization of Imp7/8 in nuclear import of SmadsXiaohao Yao
Program in Molecular Medicine, University of Massachusetts Medical School, Worcester, Massachusetts 01605, USA
J Biol Chem 283:22867-74. 2008..These observations suggest selective involvement of Imp8/Msk in nuclear import of different Smads under different conditions...
Identification of phosphatases for Smad in the BMP/DPP pathwayHong B Chen
Program in Molecular Medicine, University of Massachusetts Medical School, Worcester, Massachusetts 01605, USA
Genes Dev 20:648-53. 2006..We show that the mammalian PDPs are important in dephosphorylation of BMP-activated Smad1 but not TGF-beta-activated Smad2 or Smad3. Thus, PDPs specifically inactivate Smads in the BMP/DPP pathway...
Nuclear targeting of transforming growth factor-beta-activated Smad complexesHong Bing Chen
Program in Molecular Medicine, University of Massachusetts Medical School, Worcester, Massachusetts 01605, USA
J Biol Chem 280:21329-36. 2005..Indeed tumorigenic mutations in Smad4 that affect its interaction with Smad2 or Smad3 impair nuclear accumulation of Smad4 in response to TGF-beta...
