title: Catch the KIF5B train to the apical surface.
abstract: As epithelial cells become polarized, they develop new pathways to send proteins to the apical or basolateral domains of their plasma membrane. In this issue of Developmental Cell, Jaulin et al. (2007) show that as polarity develops, there is a shift in the kinesin motor protein used to transport an apical protein to the cell surface.
