Despite reports suggesting a potential role in membrane fusion, the V(0) subunit of the (+)H/ATPase has remained an unlikely candidate for the fusion pore. In this issue of Cell, Hiesinger and coworkers (Hiesinger et al., 2005) present a forward genetic screen that reveals it to be necessary for synaptic vesicle fusion, independent of its role in vesicle acidification.
尽管有报道表明(+)H/ATP酶的V(0)亚基在膜融合中可能发挥作用,但它一直不太可能是融合孔的候选者。在本期《细胞》杂志中,希辛格及其同事(希辛格等人,2005年)进行了一项正向遗传学筛选,结果表明它对于突触小泡融合是必需的,且与其在小泡酸化中的作用无关。
