Molecular Mechanisms Underlying Sperm-Eng Interaction

在海星阿斯特里亚斯·阿穆伦斯中，鸡蛋的果冻外套、命名的跨组反应诱导物质（ARIS）、共ARIS和星形氮，在特别上讨论了同源spermatozoa以使跨组反应特殊的行为。ARIS是一种类似蛋白质的化合物，将其绑定到接收器本地化到精子头的外部部分中的一个小域。它的活动在很大程度上是有影响力的，由1000个或如此重复的硫代五硫代化合物链组成。Co-ARIS是一种由硫代类固醇和五氟代乙酰胺组成的皂苷。In combination with ARIS， it increases intracellular CaイイD12+イエD1 concentration of sperm。小球藻是一组富含谷氨酰胺的四肽，具有一个不饱和连接。它增加了cGMP水平和孔隙度的pH值，通过结合其受体，即主要孔隙膜蛋白中125 kDa的瓜尼酯循环酶。

In starfish Asterias amurensis, three components in the jelly coat of eggs, namely acrosome reaction-inducing substance (ARIS), Co-ARIS and asterosap, act in concerted on homologous spermatozoa to elicit the acrosome reaction species-specifically. ARIS is proteoglycan-like compound which binds to the receptor localized to a small domain in the anterior portion of sperm heads. Its activity is mostly attributable to a sulfatedpolysaccharide chain composed of one thousand or so repeating units of a sulfated pentasaccharide. Co-ARIS is a group of saponins consisting of a sulfated steriod and a pentasaccharide. In combination with ARIS, it increases intracellular CaィイD12+ィエD1 concentration of sperm. Asterosap is a group of glutamine-rich tetratricontapeptides with a disulfide linkage. It increases cGMP level and intracellular pH of sperm through binding to its receptor that is the guanylate cyclase of 125 kDa in a major sperm membrane protein.
