Microtubules provide directional information for core PCP function.
Bottom Line: Consistent with previous results, we find that the Ft/Ds/Fj-module has an effect on a MT-cytoskeleton.We show Ft/Ds/Fj-dependent initial polarization of the apical MT-cytoskeleton prior to global alignment of the core-module, reveal that the anchoring of apical non-centrosomal MTs at apical junctions is polarized, observe that directional trafficking of vesicles containing Dsh depends on Ft, and demonstrate the feasibility of this model by mathematical simulation.Together, these results support the hypothesis that Ft/Ds/Fj provides a signal to orient core PCP function via MT polarization.
