Abstract
Ribosomes, some of which are arranged in polyribosomal configurations, are attached to specialized regions of the acrosomal membrane in guinea pig spermatids. This finding indicates a new functional dimension for the acrosomal membrane, that of protein synthesis, and suggests that during acrosome formation, proteins of the acrosomal membrane or acrosomal contents need not be synthesized before or during passage through the Golgi apparatus.
摘要
核糖体，其中一些以多核糖体的形式排列，附着在豚鼠精子细胞顶体膜的特定区域。这一发现揭示了顶体膜的一个新的功能维度，即蛋白质合成，并表明在顶体形成过程中，顶体膜或顶体内容物的蛋白质无需在通过高尔基体之前或期间合成。
