Differential roles for actin polymerization and a myosin II motor in assembly of the epithelial apical junctional complex.

abstract：:UNC-104 (KIF1A) is a kinesin motor that transports synaptic vesicles from the neuronal cell body to the terminal. Previous in vitro studies have shown that a Dictyostelium relative of UNC-104 transports liposomes containing acidic phospholipids, but whether this interaction is needed for the recognition and transport ...
