Plus end-directed motor protein involved in asymmetric cell division of sensory organ precursor (SOP) cells by playing a role in the asymmetric localization of Sara-expressing endosomes to the pIIa daughter cell but not to the pIIb cell. Targets Sara-expressing endosomes to the central spindle which is symmetrically arranged in early cell division. During late cytokinesis, central spindle asymmetry is generated by enrichment of Patronin on the pIIb side which protects microtubules from depolymerization by Klp10A while unprotected microtubules on the pIIa side are disassembled by Klp10A, leading to the asymmetric delivery of Sara-expressing endosomes to the pIIa daughter cell (PubMed:26659188). Also plays a role in regulation of autophagosome formation, fusion and positioning and is required for normal localization of Rab14 (PubMed:26763909). Interacts with Atg8a and Rab14. Diffuse movement of Sara-expressing endosomes, failed targeting of Sara-expressing endosomes to the central spindle and symmetric endosome localization in daughter SOP cells. Belongs to the TRAFAC class myosin-kinesin ATPase superfamily. Kinesin family.
