Fig. 3

Fig. 3 β-catenin protein does not localize to the nuclei of hec mutant embryos. Nuclear localization of β-catenin protein was observed in wild-type embryos on the presumptive dorsal side (a, c) but not the presumptive ventral side (b). No nuclear localization was apparent in hec mutant embryos (d–h), β-catenin localization at the membrane can be detected in both wild-type and hec mutant embryos. Animal views of sphere stage embryos (4 hpf). Panels b, c and e–h are higher magnifications of panels a and d, respectively, as indicated by the red boxes in panels a and d.
