Abstract

Resact, a peptide of known sequence isolated from the jelly layer of Arbacia punctulata eggs, is a potent chemoattractant for A. punctulata spermatozoa. The chemotactic response is concentration dependent, is abolished by pretreatment of the spermatozoa with resact, and shows an absolute requirement for millimolar external calcium. A. punctulata spermatozoa do not respond to speract, a peptide isolated from the jelly layer of Strongylocentrotus purpuratus eggs. This is the first report of animal sperm chemotaxis in response to a defined egg-derived molecule.

摘要

反应肽是一种从斑点海胆卵的胶膜中分离出来的已知序列的肽，对斑点海胆精子是一种有效的化学引诱剂。趋化反应是浓度依赖性的，用反应肽预处理精子可消除该反应，并且显示出对毫摩尔级外部钙的绝对需求。斑点海胆精子对从紫海胆卵的胶膜中分离出的肽受精素不产生反应。这是关于动物精子对特定的卵源分子产生趋化性的首次报道。
