Beta-catenin Forms Protein Aggregation at High Concentrations in HEK293TCells
Background: The canonical Wnt signal transduction (or the Wnt/β-catenin pathway) plays a crucial role in the development of animals and in carcinogenesis. Beta-catenin is the central component of this signaling pathway. The activation of Wnt/β-catenin signaling results in the cytoplasmic and nuclear accumulation of β-catenin. In the nucleus, β-catenin interacts with the TCF/LEF transcription fa...

متن کاملTC1 (C8orf4) enhances the Wnt/beta-catenin pathway by relieving antagonistic activity of Chibby.
The Wnt/beta-catenin pathway has been implicated in human cancers. Here, we show that TC1 (C8orf4), a small protein present in vertebrates, functions as a positive regulator of the pathway. TC1 interacts with Chibby (Cby) and thereby enhances the signaling pathway by relieving the antagonistic function of Cby on the beta-catenin-mediated transcription. Upon coexpression in mammalian cells, TC1 ...
متن کاملRanBP3 enhances nuclear export of active β-catenin independently of CRM1
beta-Catenin is the nuclear effector of the Wnt signaling cascade. The mechanism by which nuclear activity of beta-catenin is regulated is not well defined. Therefore, we used the nuclear marker RanGTP to screen for novel nuclear beta-catenin binding proteins. We identified a cofactor of chromosome region maintenance 1 (CRM1)-mediated nuclear export, Ran binding protein 3 (RanBP3), as a novel b...
متن کاملPygopus and legless provide essential transcriptional coactivator functions to armadillo/beta-catenin.
Wnt signaling controls important aspects of animal development, and its deregulation has been causally linked to cancer. Transduction of Wnt signals entails the association of beta-catenin with nuclear TCF DNA binding proteins and the subsequent activation of target genes. The transcriptional activity of Armadillo (Arm, the Drosophila beta-catenin homolog) largely depends on two recently discov...
