Figure 8


Fig. 8. The Kra AA-boxes 1 and 2 are essential for Kra functionality in vivo. When expressed under the control of the panneuronal driver C155-GAL4, neither UAS-HA-kra12A nor UAS-HA-kra7A rescues the kra1/kra2 mutant phenotype at the midline (n=312 and 360, respectively). Note that UAS-HA-kraWT significantly attenuates the midline crossing phenotype (see Fig. 4F,L).
