    ..We therefore conclude the NMY-2 is required for establishing cellular polarity in C. elegans embryos. ..

    ..Proteins including Rho GTPase activating protein/CYK-4 and late CYK-1, which are required for late stages of cytokinesis, function downstream of LET-502 and MEL-11. ..

    ..These findings provide a model for how PAR and MEX proteins convert a transient asymmetry into a stably polarized axis. ..

    ..Similar actomyosin flows accompany the establishment of PAR asymmetries that form after the one-cell stage, suggesting that actomyosin-mediated cortical flows have a general role in PAR asymmetry. ..

    ..We discuss our findings in the context of other studies suggesting that FH genes in yeast and insects function early in cytokinesis to assemble a cleavage furrow. ..

    ..Finally, during a signaling-induced asymmetric cell division, NMY-2 is required for SRC-dependent phosphotyrosine signaling and acts in parallel with WNT-signaling to specify endoderm. ..

    ..We show that SAND-1 is essential for RAB-7 function at the transition from early to late endosomes, but not for RAB-7 function at lysosomes. ..

    ..Other IP(3)-mediated processes, e.g., defecation, were unaffected. Thus it appears that interactions between IP(3)Rs and myosin are required for maintaining the specificity of IP(3) signalling in C. elegans and probably more generally. ..

    ..Both proteins have been implicated in homotypic ER membrane fusion. We provide evidence that homotypic membrane fusion is required to form the sheet structure in the early embryo. ..
