We report the identification of a putative v-SNARE (GOS-28), localized primarily to transport vesicles at the terminal rims of Golgi stacks. In vitro, GOS-28, A Golgi SNARE of 28 kD, is efficiently packaged into Golgi-derived vesicles, which are most likely COPI coated. Antibodies directed against GOS-28 block its ability to bind alpha-SNAP, partially inhibit transport from the cis to the medial cisternae, and do not inhibit budding of COP-coated vesicles, but do accumulate docked uncoated vesicles.
我们报告了一种假定的v-SNARE(GOS-28)的鉴定结果,其主要定位于高尔基体堆栈末端边缘的运输小泡。在体外,28kD的高尔基体SNARE GOS-28能高效地包装到源自高尔基体的小泡中,这些小泡很可能被COP I包被。针对GOS-28的抗体阻断其与α-SNAP结合的能力,部分抑制从顺面到中间潴泡的运输,不抑制COP包被小泡的出芽,但会使停靠的无包被小泡积累。
