| Research Abstract |
Cell polarization is crucial for a variety of processes in development. The Par3/Par6/aPKC (Par aPKC) complex is required for polarity establishment in several types of cell. During the process, the Par aPKC complex is targeted to the plasma membrane, which plays an important role in cell polarization. However, little is known about the mechanisms underlying proper subcellular localization of the complex. In the present study, we identify a novel Par3-binding protein, which recruits the Par aPKC complex to the plasma membrane for regulating mammalian epithelial cell polarity.
