A new type of polysialic acid (polySia) structure was demonstrated to occur in a major unknown sialoglycoprotein with a diverse molecular mass of 40-80 kDa in sea urchin sperm. The polySia-containing glycan structure was determined to be HSO3→8Neu5Acα2→9(Neu5Acα2→9 n-2 Neu5Acα2→6GalNAcα1→Ser/Thr (n, on average 15), based on carbohydrate analysis of the sialoglycopeptide obtained by an exhaustive protease digestion of whole sperm, fluorometric anion-exchange high-performance liquid chromatography, and methylation analysis. The sulfate group was predominantly localized to the nonreducing terminus of the polySia chain. This is the first example of an α2,9-linked polySia structure in animal sperm. The polySia-containing sialoglycoprotein was present in sperm flagellum but not in the head. Furthermore, this sialoglycoprotein localized in the sperm lipid raft, which contains an enriched ganglioside (Neu5Acα 2→8Neu5Acα2→6GlcCer), a receptor for sperm-activating peptide (speract), and its associated guanylate cyclase. © Oxford University Press 2004; all rights reserved.
