Dynamin family members have been implicated in exocytosis. Vps1 (the yeast dynamin homolog) mutant vacuoles show decreased fusion and trans ‐Soluble N ‐ethylmaleimide sensitive factor Attachment Protein Receptor ( SNARE ) complex formation but comparable hemifusion relative to wild type. Vps1, through its oligomerization and SNARE ‐domain binding, brings together multiple t‐ SNAREs . This finding uncovers a novel function of Vps1 in coordinating the hemifusion – content mixing transition in yeast vacuole fusion.
