| Research Abstract |
To understand the molecular mechanism of the PAR-aPKC polarity complex to regulate cell polarity, we identified ASPP2 as a novel member of the PAR-aPKC polarity complex. ASPP2 as well as PAR3 localizes to the apical junctional complex of epithelial cells and their localization are mutually-dependent.Another finding involves a novel regulatory system for the exocytosis of apical membrane proteins by the PAR-aPKC polarity complex. We identified KIBRA as a competitive inhibitor of aPKC kinase activity. Further studies revealed that KIBRA suppress apical exocytosis through inhibition of the aPKC kinase activity.
