Abstract

Dishevelled (Dsh/Dvl) proteins are known to mediate Wnt signaling by up-regulating beta-catenin levels and stimulating T cell factor (TCF)/LEF-1-dependent transcription. We have identified a new Dvl-mediated signaling pathway in that mouse Dvl proteins, when expressed in COS-7 cells, stimulate c-Jun-dependent transcription activity and the kinase activity of the c-Jun N-terminal kinase (JNK). The DEP domain of Dvl1 is essential for JNK activation. By contrast, all three conserved domains of Dvl, including DIX, PDZ, and DEP, are required for up-regulation of beta-catenin and for stimulation of LEF-1-mediated transcription in mammalian cells. Thus, Dvl can lead to two different signaling pathways. Furthermore, the small G proteins of Cdc42 or Rac1, which are involved in JNK activation by many stimuli, do not appear to play a major role in Dvl-mediated JNK activation, because the dominant negative mutants of Cdc42 and Rac1 could not inhibit Dvl-induced JNK activation. This suggests that Dvl may activate JNK via novel pathways.

  • The second branch of signaling requires the DEP domain of Dsh and activates the Rac GTPase, independent of Daam1, and activated Rac stimulates JNK activity.

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.
