In exocytosis, secretory granules contact plasma membrane at sites where microdomains can be observed, which are sometimes marked by intramembranous particle arrays. Such arrays are particularly obvious when membrane fusion is frozen at a subterminal stage, e.g., in neuromuscular junctions and ciliate exocytotic sites. In Paramecium, a genetic approach has shown that the "rosettes" of intramembranous particles are essential for stimulated exocytosis of secretory granules, the trichocysts. The id ...[more]
