摘要

Syntaxin-1和25-kDa突触体相关蛋白(SNAP-25)存在于几种不同的分泌细胞类型的质膜中，并参与胞吐过程。本文研究了自由生活变形虫的超微结构、结构膜蛋白以及Syntaxin-1和SNAP-25等蛋白。我们通过扫描电子显微镜获得的结果显示，在没有膜的变形虫中，有许多膜突起和一些孔状结构。利用免疫细胞化学方法，我们发现了结构蛋白Syntaxin-1和SNAP-25。

Ultrastructural analysis and identification of membrane proteins in the free-living amoeba Difflugia corona.

Syntaxin-1 and 25-kDa Synaptosome-associated Protein (SNAP-25) are present in the plasma membrane of several different secretory cell types and are involved in the exocytosis process. In this work, the free-living amoeba Difflugia corona was studied in relation to ultrastructure, structural membrane proteins, and proteins such as Syntaxin-1 and SNAP-25. Our results obtained by scanning electron microscopy in the amoeba without its theca, showed many membrane projections and several pore-like structures. Using immunocytochemistry, we found structural proteins Syntaxin-1 and SNAP-25.
