Journal ArticleDOI
Targeted disruption of SMAD3 results in impaired mucosal immunity and diminished T cell responsiveness to TGF-β
Xiao Yang,John J. Letterio,Robert J. Lechleider,Lin Chen,Russ Hayman,Hua Gu,Anita B. Roberts,Chu-Xia Deng +7 more
TL;DR: The data suggest that SMAD3 has an important role in TGF‐β‐mediated regulation of T cell activation and mucosal immunity, and that the loss of these functions is responsible for chronic infection and the lethality of Smad3‐null mice.
Journal ArticleDOI
The Immunophilin FKBP12 Functions as a Common Inhibitor of the TGFβ Family Type I Receptors
Tongwen Wang,Bi-Yu Li,Paul D. Danielson,Paresh C. Shah,Sybil Rockwell,Robert J. Lechleider,Jennifer Martin,Thomas F. Manganaro,Patricia K. Donahoe +8 more
TL;DR: Overexpression of a myristylated FKBP12 in Mv1Lu cell specifically inhibits two separate pathways activated by TGF beta, and two point mutations on FkBP12 abolish the inhibitory activity, suggesting that FK BP12 may dock a cytoplasmic protein to the type I receptors to inhibit TGFbeta family mediated signaling.
Journal ArticleDOI
Smad2 transduces common signals from receptor serine–threonine and tyrosine kinases
Mark P. de Caestecker,W. Tony Parks,Chistopher J. Frank,Paola Castagnino,Donald P. Bottaro,Anita B. Roberts,Robert J. Lechleider +6 more
TL;DR: It is demonstrated here that HGF and EGF, which signal through RTKs, can also mediate SMAD-dependent reporter gene activation and induce rapid phosphorylation of endogenous SMAD proteins by kinase(s) downstream of MEK1.
Journal ArticleDOI
A novel mitochondrial septin-like protein, ARTS, mediates apoptosis dependent on its P-loop motif.
Sarit Larisch,Youngsuk Yi,Rona Lotan,Hedviga Kerner,Sarah Eimerl,W. Tony Parks,Yossi Gottfried,Stephanie Birkey Reffey,Mark P. de Caestecker,David Danielpour,Naomi Book-Melamed,Rina Timberg,Colin S. Duckett,Robert J. Lechleider,Robert J. Lechleider,Hermann Steller,Joseph Orly,Seong-Jin Kim,Anita B. Roberts +18 more
TL;DR: A protein product of the human septin H5/PNUTL2/CDCrel2b gene called ARTS (for apoptosis-related protein in the TGF-β signalling pathway) was described in this article.
Journal ArticleDOI
Targeted Mutagenesis of Smad1 Reveals an Essential Role in Chorioallantoic Fusion
Robert J. Lechleider,Julie L. Ryan,Lisa Garrett,China Eng,Chu-Xia Deng,Anthony Wynshaw-Boris,Anita B. Roberts +6 more
TL;DR: The data demonstrate that although highly similar structurally, Smad proteins are not functionally homologous, and suggest that the defect observed in the developing extraembryonic tissue is caused by a very specific loss of transcriptional activity regulated by Smad1.
