Text-mined interactions from Literome
Fukata et al., Mol Cell Biol 2001
:
We have previously proposed that
IQGAP1 , an effector of Rac1 and Cdc42, negatively regulates cadherin mediated cell-cell adhesion by interacting with beta-catenin and by causing the dissociation of alpha-catenin from cadherin-beta-catenin-alpha-catenin complexes and that activated Rac1 and Cdc42 positively
regulate cadherin mediated cell-cell adhesion by inhibiting the interaction of IQGAP1 with
beta-catenin
Sugimoto et al., J Hum Genet 2001
(Stomach Neoplasms) :
IQGAP1 has been reported to encode a ras GAP related protein, and its interaction with cadherin and/or
beta-catenin induces a dissociation of beta-catenin from the cadherin-catenin complex, one of the mechanisms for cell-cell adhesion
Briggs et al., J Biol Chem 2002
:
The recently discovered calmodulin binding protein
IQGAP1 binds stoichiometrically to beta-catenin and
regulates the association of
beta-catenin with the cell-cell adhesion complex
Noritake et al., Mol Biol Cell 2004
:
We here found that suppression of
IQGAP1 , an actin binding protein and an effector of Rac1, by small interfering RNA apparently
reduced the accumulation of actin filaments, E-cadherin, and
beta-catenin at sites of cell-cell contact in Madin-Darby canine kidney II epithelial cells under the conditions in which knockdown of Rac1 reduced them

IQGAP1 or N-cadherin
