Updated publication reference for PubMed record(s): 30021165. The mechanisms by which motor proteins are loaded on vesicles and how cargos are captured at appropriate sites remain unclear. To better understand how KIF1A-based transport is regulated, we identified the KIF1A interactome and focused on three binding partners, the calcium binding protein Calmodulin (CaM) and two synaptic scaffolding proteins: liprin-a and TANC2.
