Research Abstract

Epithelial cells cover the boundary between our body and external environment, and thus develop functional asymmetry (polarity) between the cell membranes facing internal and external environment. It has been demonstrated that abnormal epithelial polarity leads to physiological deficiency. In this study, we have analyzed how the general cell polarity-regulating protein, PAR-1, plays important roles for epithelial polarity, especially by analyzing its binding proteins.
