Rab8a and Rab11a function through the exocyst to target Par3 to the apical surface, and control apical Cdc42 activation through the Cdc42 GEF, Tuba

:
Cdc42 deficiency impaired Rab8a activation and its association with multiple effectors, and prevented trafficking of Rab8a vesicles to the midbody ... Rab8a was also required for Cdc42-GTP activity in the intestinal epithelium, where continued cell division takes place
