Abstract
The Wnt signalling cascade is a highly conserved signalling pathway throughout the animal kingdom. In Xenopus, Wnt signalling functions in mesodermal dorsoventral patterning. Earlier work on deciphering the components of the wnt signalling cascade left a gap between cytosolic β‐catenin, the final member of the cascade, and the nuclear target genes. Several recent papers now reveal how the Wnt signal is transmitted into the nucleus. Surprisingly, β‐catenin directly interacts with the transcription factor LEF‐1/XTCF‐3, and thereby is not only translocated into the nucleus but also modulates the properties of LEF‐1/XTCF‐3 as a transcription factor(1–5).Keywords
