    ..LGL-1 negatively regulates the accumulation of myosin (NMY-2) on the posterior cortex, representing a possible mechanism by which LGL-1 might contribute to polarity maintenance. ..

A novel adapter protein employs a phosphotyrosine binding domain and exceptionally basic N-terminal domains to capture and localize an atypical protein kinase C: characterization of Caenorhabditis elegans C kinase adapter 1, a protein that avidly bin. J Biol Chem. 2001;276:10463-75 pubmed
    ..Thus, a PTB domain and PSDs collaborate in a novel fashion in CKA1/CKA1S to enable tethering and targeting of PKC3. Avid ligation of a PKC isoform is a previously unappreciated function for a PTB module. ..

    ..Our data suggest that the expression of RPN-2 is involved in the mechanism to suppress nuclear-centrosome rotation in symmetrically dividing cells and it may work in cooperation with PKC-3. ..

    ..We propose that PAR-3 activity is required for the proper polarization of spermathecal cells and that defective ovulation results from defective distal spermathecal development. ..

    ..We conclude that PAR-6 binding to PKC-3, but not to PAR-3 nor to a conventional PDZ ligand, is required for PAR-6 cortical localization and function in C. elegans. ..
  9. Hao Y, Boyd L, Seydoux G. Stabilization of cell polarity by the C. elegans RING protein PAR-2. Dev Cell. 2006;10:199-208 pubmed
    ..Our findings suggest that reciprocal inhibitory interactions among PAR proteins stabilize polarity by reinforcing an initial asymmetry in PKC-3. ..
