Late secretory t-SNARE protein required for secretion and proper cytokinesis. Plays an important role in the secretion of virulence-associated extracellular enzymes and vesicle-mediated polarized hyphal growth. Leads to defects in secretion of degradative enzymes and defects in hyphal extension. Leads also to the Spitzenkoerper dissipation and accumulation of secretory vesicles. Belongs to the syntaxin family.
