SARA, a FYVE Domain Protein that Recruits Smad2 to the TGFβ Receptor [PDF]

open access: yesCell, 1998
Smads transmit signals from transmembrane ser/thr kinase receptors to the nucleus. We now identify SARA (for Smad anchor for receptor activation), a FYVE domain protein that interacts directly with Smad2 and Smad3. SARA functions to recruit Smad2 to the TGFbeta receptor by controlling the subcellular localization of Smad2 and by interacting with the ...

Platelets possess functional TGF-β receptors and Smad2 protein

open access: yesPlatelets, 2007
TGF-beta1 plays a main role in tissue repair by regulating extracellular matrix production and tissue granulation. Platelets are one of the main sources of this cytokine in the circulation. The aim of this study was to evaluate the presence of the TGF-beta receptors on platelets, the effect of TGF-beta1 on platelet aggregation and the underlying ...

Effect of the different phosphorylated Smad2 protein localizations on the invasive breast carcinoma phenotype

open access: yesApmis, 2007
Smad2 participates in the TGF‐β signaling pathway, where it cooperates with transcription factors to regulate expression of defined genes. The purpose of this study was to investigate the expression pattern of phosphorylated Smad2 (pSmad2) in association with clinicopathological parameters and biological markers of proliferation and invasion ...

Expression and localization of Smad2 and Smad4 proteins in the porcine ovary

Acta Histochemica, 2014
The objective of the present study was to investigate the temporal and spatial expression of Smad2 and Smad4 proteins, the downstream signaling molecules of the transforming growth factor beta (TGF-β) superfamily, in the porcine ovary. Cellular localization of Smad2 and Smad4 proteins was examined using immunohistochemistry.

Smad2 Protein Disruption in the Central Nervous System Leads to Aberrant Cerebellar Development and Early Postnatal Ataxia in Mice [PDF]

open access: yesJournal of Biological Chemistry, 2011
Smad2 is a critical mediator of TGF-β signals that are known to play an important role in a wide range of biological processes in various cell types. Its role in the development of the CNS, however, is largely unknown. Mice lacking Smad2 in the CNS (Smad2-CNS-KO) were generated by a Cre-loxP approach.

Immunolocalisation and expression of Smad2 and Smad4 proteins in dog testis during postnatal development.

Andrologia, 2011
The expression and localisation of downstream signalling molecules of transforming growth factor beta superfamily, Smad2 and Smad4 proteins, was investigated in immature and mature dog testis. Cellular localisation of Smad2 and Smad4 proteins was examined using immunohistochemistry.

Protein tyrosine phosphatase 1B regulates TGFβ1-induced Smad2 activation through PI3 kinase-dependent pathway

Cytokine, 2006
Insulin is known to modulate transforming growth factor-beta (TGFbeta) signaling. In this report, by using the IN Cell Analyzer 1000, the fluorescence cell imaging instrument, we demonstrated that protein tyrosine phosphatase 1B (PTP1B) could regulate TGFbeta1-induced Smad2 activation in a PI3 kinase-dependent manner.

Possible involvement of protein kinases and Smad2 signaling pathways on osteoclast differentiation enhanced by activin A

Journal of Cellular Physiology, 2001
AbstractBone tissues reportedly contain considerable amounts of activin A and follistatin, an activin A‐binding protein. In the present study, we found that follistatin strongly inhibited osteoclast formation in cocultures of mouse bone marrow cells and primary osteoblasts induced by 1α,25 dihydroxyvitamin D3, prostaglandin E2, and interleukin‐1α ...
