Analysis of the role of the Rac/Cdc42 GTPases during planar cell polarity generation in Drosophila.

Abstract excerpt

Initial genetic studies in Drosophila suggested that several members of the Rho subfamily (RhoA, Rac1 and Cdc42) are involved in planar cell polarity (PCP) establishment. However, analyses of Rac1, Rac2 and Mtl loss-of-function (LOF) mutants have argued against their role in this process. Here, we investigate in detail the role of the Rho GTPases Mtl, Cdc42, Rac1 and Rac2 in PCP generation. These functional...
