ΔArm and GFPαNcat rescue the defects caused by dominant-negative α-catenin mutants. (A, B, and C) αNcatNtermGFP + GFP, ΔArm, or GFPαNcat, respectively. (D–F) GFPαNcatNterm + GFP, ΔArm, or GFPαNcat. In all cases, 0.3 ng of αNcatNtermGFP or GFPαNcatNterm mRNA was coinjected with 1.2 ng of the second mRNA. Mutants in A and D do not develop further than gastrulation. Rescued mutants gastrulate (B and C, and E and F) and continue to develop normally. mRNA was injected into the animal pole of one cell of two-cell embryos.
