Abstract

The cytoplasmic proteins beta-catenin of vertebrates and armadillo of Drosophila have two functions: they link the cadherin cell-adhesion molecules to the cytoskeleton, and they participate in the wnt/wingless signal pathway. Here we show, in a yeast two-hybrid screen, that the architectural transcription factor LEF-1 (for lymphoid enhancer-binding factor) interacts with beta-catenin. In mammalian cells, coexpressed LEF-1 and beta-catenin form a complex that is localized to the nucleus and can be detected by immunoprecipitation. Moreover, LEF-1 and beta-catenin form a ternary complex with DNA that splays an altered DNA bend. Microinjection of LEF-1 into XenoPus embryos induces axis duplication, which is augmented by interaction with beta-catenin. Thus beta-catenin regulates gene expression by direct interaction with transcription factors such as LEF-1, providing a molecular mechanism for the transmission of signals, from cell-adhesion components or wnt protein to the nucleus.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
