AbstractHuman fertilization begins when spermatozoa bind to the extracellular matrix coating of the oocyte, known as the zona pellucida (ZP). One spermatozoan then penetrates this matrix and fuses with the egg cell, generating a zygote. Although carbohydrate sequences on the ZP have been implicated in sperm binding, the nature of the ligand was unknown. Here, ultrasensitive mass spectrometric analyses revealed that the sialyl-Lewis x sequence [NeuAcα2-3Galβ1-4(Fucα1-3)GlcNAc], a well-known selectin ligand, is the most abundant terminal sequence on the N- and O-glycans of human ZP. Sperm-ZP binding was largely inhibited by glycoconjugates terminated with sialyl-Lewis x sequences or by antibodies directed against this sequence. Thus, the sialyl-Lewis xsequence represents the major carbohydrate ligand for human sperm-egg binding.

This work was supported by the Biotechnology and Biological Sciences Research Council (BBSRC), grant BBF0083091 (to A. D., H. R. M., and S. M. H.); a Royal Society International Joint Project Award (to A. D. and K-H. K.); the Breeden-Adams Foundation and a Life Sciences Mission Enhancement Reproductive Biology Program funded by the state of Missouri (to G. F. C.); and the University Research Committee, University of Hong Kong (to P.C.N. and W.S.B.Y). The proteomics and sulfoglycomics data were acquired at the National Research Program for Genomic Medicine (NRPGM) Core Facilities for Proteomics and Glycomics funded by the Taiwan National Science Council (NSC99-3112-B-001-025).
