pubmed:abstractText |
In this paper we describe a mild procedure which results in the extraction of a glycoprotein fraction from the vitelline coat (VC) of Ciona intestinalis while leaving behind the bulk of the VC components. When acting upon the spermatozoa this fraction inhibits sperm binding to the VC and fertilization and elicits sperm activation including the acrosome reaction. SDS-PAGE shows that it contains the same (fucosyl) glycoprotein components previously recognized in the total extracts of VC. It is suggested that this material contains the sperm receptors or those components of the receptors that are essential for their Chinese function.
