CTNNB1 bound to CDH1 inhibits CTNNB1. 8 / 8

reach
"Hence, a reduced binding affinity between beta-catenin and E-cadherin is expected to increase the signaling pool of beta-catenin, possibly leading to enhanced nuclear signaling."

reach
"E-cadherin binding to beta-catenin prevents nuclear localization of beta-catenin and beta-catenin and LEF-1-mediated transactivation [XREF_BIBR, XREF_BIBR]."

reach
"The CagA and E-cadherin interaction impairs the complex formation between E-cadherin and beta-catenin, causing cytoplasmic and nuclear accumulation of beta-catenin."

reach
"In the stomach, CagA physically interacts with E-cadherin and impairs the complex formation between E-cadherin and beta-catenin, causing cytoplasmic and nuclear accumulation of beta-catenin."

reach
"In CAC, E-cadherin forms a complex with beta-catenin and in combination with the actin cytoskeleton prevents nuclear translocation of beta-catenin, thus regulating the activity of the Wnt and catenin signaling pathways [XREF_BIBR]."

reach
"However, upon infection with CagA positive H. pylori strains, CagA will become competitive in combination with E-cadherin and disrupt complex formation between E-cadherin and beta-catenin, causing cytoplasmic and nuclear accumulation of beta-catenin."

reach
"Binding of beta-catenin and E-cadherin at the cell junction is indicative of the antagonism of the Wnt pathway restricting nuclear translocation of beta-catenin XREF_BIBR."

reach
"Indeed, disruption of E-cadherin and beta-catenin complexes leads to the loss of epithelial polarization and allows nuclear translocation of beta-catenin."
