Arabidopsis myosin XIK interacts with the exocyst complex to facilitate vesicle tethering during exocytosis
Myosin motors are essential players in secretory vesicle trafficking and exocytosis in yeast
and mammalian cells; however, similar roles in plants remain a matter for debate, at least for
diffusely growing cells. Here, we demonstrate that Arabidopsis (Arabidopsis thaliana)
myosin XIK, via its globular tail domain (GTD), participates in the vesicle tethering step of
exocytosis through direct interactions with the exocyst complex. Specifically, myosin XIK
GTD bound directly to several exocyst subunits in vitro and functional fluorescently tagged …
