... embryogenesis, we have initiated an analysis of glycosyltransferase function using the zebrafish system. In this study, we report the characterization of a zebrafish β1,4-galactosyltransferase(GalT), which has substantial homology with mammalian β4GalT5 and is expressed zygotically throughout the zebrafish...

... evidence; however, the effects on fertilization of targeted mutations in any of these candidate receptors have not yet been reported. In this paper, we describe the effects of targeted mutations in β1,4-galactosyltransferase, the best studied of the candidate receptors for ZP3. Surprisingly, galactosyl...

...David J. Miller; Xiaohai Gong; Barry D. Shur ABSTRACT Fertilization in the mouse is initiated by sperm 1,4-galactosyltransferase (GalTase) binding to terminal N -acetylglucosamine residues on the zona pellucida glyco-protein ZP3. Binding of ZP3 induces exocytosis of the sperm acrosome, whose...
