Armadillo Coactivates Transcription Driven by the Product of the Drosophila Segment Polarity Gene dTCF
- M. Wetering, R. Cavallo, +10 authors H. Clevers
- Biology, Medicine
- Cell
- 21 March 1997
The vertebrate transcription factors TCF (T cell factor) and LEF (lymphocyte enhancer binding factor) interact with beta-catenin and are hypothesized to mediate Wingless/Wnt signaling. We have cloned… Expand
Negative regulation of Armadillo, a Wingless effector in Drosophila.
- L. Pai, S. Orsulic, A. Bejsovec, M. Peifer
- Biology, Medicine
- Development
- 1 June 1997
Drosophila Armadillo and its vertebrate homolog beta-catenin play essential roles both in the transduction of Wingless/Wnt cell-cell signals and in the function of cell-cell adherens junctions.… Expand
The positioning and segregation of apical cues during epithelial polarity establishment in Drosophila
- Tony J. C. Harris, M. Peifer
- Biology, Medicine
- The Journal of cell biology
- 29 August 2005
Cell polarity is critical for epithelial structure and function. Adherens junctions (AJs) often direct this polarity, but we previously found that Bazooka (Baz) acts upstream of AJs as epithelial… Expand
Wnt signaling in oncogenesis and embryogenesis--a look outside the nucleus.
- M. Peifer, P. Polakis
- Biology, Medicine
- Science
- 3 March 2000
The Wnt cell-cell signaling pathway plays a critical and evolutionarily conserved role in directing cell fates during embryogenesis. In addition, inappropriate activation of the Wnt signal… Expand
Drosophila Tcf and Groucho interact to repress Wingless signalling activity
- R. Cavallo, R. Cox, +5 authors A. Bejsovec
- Biology, Medicine
- Nature
- 8 October 1998
Wingless/Wnt signalling directs cell-fate choices during embryonic development,. Inappropriate reactivation of the pathway causes cancer. In Drosophila, signal transduction from Wingless stabilizes… Expand
Adherens junction-dependent and -independent steps in the establishment of epithelial cell polarity in Drosophila
- Tony J. C. Harris, M. Peifer
- Biology, Medicine
- The Journal of cell biology
- 11 October 2004
Adherens junctions (AJs) are thought to be key landmarks for establishing epithelial cell polarity, but the origin of epithelial polarity in Drosophila remains unclear. Thus, we examined epithelial… Expand
An in vivo structure-function study of armadillo, the beta-catenin homologue, reveals both separate and overlapping regions of the protein required for cell adhesion and for wingless signaling
- S. Orsulic, M. Peifer
- Biology, Medicine
- The Journal of cell biology
- 1 September 1996
Armadillo, the Drosophila homologue of vertebrate beta-catenin, plays a pivotal role both in Wingless signaling and in assembly of adherens junctions. We performed the first in vivo… Expand
The Drosophila afadin homologue Canoe regulates linkage of the actin cytoskeleton to adherens junctions during apical constriction
- Jessica K. Sawyer, Nathan J. Harris, K. Slep, U. Gaul, M. Peifer
- Biology, Medicine
- The Journal of cell biology
- 13 July 2009
Cadherin-based adherens junctions (AJs) mediate cell adhesion and regulate cell shape change. The nectin–afadin complex also localizes to AJs and links to the cytoskeleton. Mammalian afadin has been… Expand
wingless signal and Zeste-white 3 kinase trigger opposing changes in the intracellular distribution of Armadillo.
- M. Peifer, D. Sweeton, M. Casey, E. Wieschaus
- Biology, Medicine
- Development
- 1 February 1994
wingless/wnt-1 signaling directs cell fate during development. Genetic analysis in Drosophila identified genes that may encode components of the wingless signal transduction system. Drosophila… Expand
A role for the Drosophila segment polarity gene armadillo in cell adhesion and cytoskeletal integrity during oogenesis.
- M. Peifer, S. Orsulic, D. Sweeton, E. Wieschaus
- Biology, Medicine
- Development
- 1 August 1993
The epithelial sheet is a structural unit common to many tissues. Its organization appears to depend on the function of the multi-protein complexes that form adherens junctions. Elegant cell… Expand
