The polarization of the anterior-posterior axis (A-P) of the Caenorhabditis elegans zygote depends on the activity of the par genes and the presence of intact microfilaments. Functional links between the PAR proteins and the cytoskeleton, however, have not been fully explored. It has recently been shown that in mammalian cells, some PAR homologs form a complex with activated Cdc42, a Rho GTPase that is implicated in the control of actin organization and cellular polarity. A role for Cdc42 in the establishment of embryonic polarity in C. elegans has not been described.
