title: W(h)ither default? Sorting and polarization in epithelial cells.
abstract: The discovery of basolateral sorting signals in the past year may leave the default pathway with nowhere to go. With new results suggesting that even more GTP-binding proteins and coatamers might be involved in transport and targeting, it is clear that the age of mapmaking in polarization research is nearly over.
