In the canonical Wnt pathway, ␤-catenin acts as a key coactivator that stimulates target gene expression through interaction with Tcf/Lef transcription factors. Its nuclear accumulation is the hallmark of active Wnt signaling and is frequently associated with cancers. Chibby (Cby) is an evolutionarily conserved molecule that represses ␤-catenin– dependent(More)
beta-Catenin functions in both cell-cell adhesion and as a transcriptional coactivator in the canonical Wnt pathway. Nuclear accumulation of beta-catenin is the hallmark of active Wnt signaling and is frequently observed in human cancers. Although beta-catenin shuttles in and out of the nucleus, the molecular mechanisms underlying its translocation remain(More)
BACKGROUND The Wnt/beta-catenin signaling pathway plays crucial roles in embryonic development and in maintenance of organs and tissues in adults. Chibby (Cby) is an evolutionarily conserved molecule that physically interacts with the key downstream coactivator beta-catenin and represses its transcriptional activation potential. Although Cby harbors a(More)
