  • Title: Egg jelly components responsible for histone degradation and acrosome reaction in the starfish, Asterina pectinifera.
    Author: Amano T, Okita Y, Okinaga T, Matsui T, Nishiyama I, Hoshi M.
    Journal: Biochem Biophys Res Commun; 1992 Aug 31; 187(1):274-8. PubMed ID: 1520308.
    Abstract:
    In the starfish, Asterina pectinifera, egg jelly induces the degradation of sperm histones as well as the acrosome reaction. We have isolated histone degradation-inducing components from the egg jelly. The histone degradation and the acrosome reaction are induced by a co-operative action of ARIS, which is an extremely large, sulfated glycoprotein with diffusible substance(s) in the jelly. Co-ARIS I, a steroidal saponin of the jelly, is effective to induce both reactions in the presence of ARIS.
