Abstract

Intracellular transport mediated by kinesin superfamily proteins (KIFs) is a highly regulated process. The molecular mechanism of KIFs binding to their respective cargoes remains unclear. We report that KIF13A is a novel plus end-directed microtubule-dependent motor protein and associates with β1-adaptin, a subunit of the AP-1 adaptor complex. The cargo vesicles of KIF13A contained AP-1 and mannnose-6-phosphate receptor (M6PR). Overexpression of KIF13A resulted in mislocalization of the AP-1 and the M6PR. Functional blockade of KIF13A reduced cell surface expression of the M6PR. Thus, KIF13A transports M6PR-containing vesicles and targets the M6PR from TGN to the plasma membrane via direct interaction with the AP-1 adaptor complex.
