Constitutively active mutant. Decreases GTPase activity. Disrupts the trafficking of CDH1 to the plasma membrane and promotes accumulation of CDH1 in RAB11A endosomes in nonpolarized cells. Promotes mistargeting of CDH1 to the apical membrane in polarized cells.
Mutagenesis site occurs in NX_P62491-2 at amino acids 70 - 70.
