在半融合/半裂变中间体处,膜融合和裂变的拮抗反应的会聚产生了一个迷人的谜,即SNARE和发动蛋白是否分别在裂变和融合中具有不寻常的反作用。SNARE介导的融合和动力蛋白驱动的分裂是已知在普遍存在的细胞通信事件(例如胞吐、胞吞和囊泡运输)期间发生的基本膜通量反应。在这里,我们证明了发动蛋白同系物Vps 1的脂质混合和内容物混合酵母液泡的性质,并纳入融合复合物的SNARE的影响。我们提出了一个新的概念,Vps 1,通过其寡聚化和SNARE结构域结合,促进半融合内容物混合过渡酵母液泡融合的trans-SNARE的数量增加。
The convergence of the antagonistic reactions of membrane fusion and fission at the hemifusion/hemifission intermediate has generated a captivating enigma of whether SNAREs and dynamin have unusual counter-functions in fission and fusion respectively. SNARE-mediated fusion and dynamin-driven fission are fundamental membrane flux reactions known to occur during ubiquitous cellular communication events such as exocytosis, endocytosis and vesicle transport. Here we demonstrate the influence of the dynamin homolog Vps1 on lipid mixing and content mixing properties of yeast vacuoles, and on the incorporation of SNAREs into fusogenic complexes. We propose a novel concept that Vps1, through its oligomerization and SNARE domain binding, promotes the hemifusion-content mixing transition in yeast vacuole fusion by increasing the number of trans-SNAREs.
