Fig. 8.
-Na+K+ ATPase localization in nok
mutants and Nok localization in snk mutants appears normal. (A,B) a6F
antibody labeling (green) at 24 hpf in horizontal section through midbrain and
hindbrain of wild type (A) and nok mutant (B) with phalloidin-Texas
Red as counterstain (red). Note that while the nok mutant hindbrain
ventricle is severely reduced, a6F antibody still labels apical membrane.
(C,D) Nok antibody labeling (green) at 24 hpf in horizontal section through
midbrain and hindbrain of wild type (C) and snk mutant (D), with
phalloidin-Texas Red as counterstain (red). Nok localizes at the apical
membrane in both wild type (C) and mutant (D), suggesting that Snk is not
necessary for Nok targeting to apical surface. Note: the snk mutant
does have normal hinge-points in the midbrain and hindbrain, although they are
not present in the optical section shown in D. Scale bar: 50 µm.
