[HTML][HTML] Oocyte Galα1, 3Gal Epitopes Implicated in Sperm Adhesion to the Zona Pellucida Glycoprotein ZP3 Are Not Required for Fertilization in the Mouse (∗)

AD Thall, P Malý, JB Lowe - Journal of Biological Chemistry, 1995 - ASBMB
The Galα1→ 3Gal structure is displayed on the zona pellucida glycoprotein ZP3 on murine
oocytes. This trisaccharide has been implicated in sperm-zona pellucida adhesive events
thought to be essential to fertilization in the mouse. To determine directly if this molecule is
required for fertilization, we have generated mice that are deficient in a gene (α1, 3GT)
encoding the UDP-Gal: β-D-Gal-α1→ 3Gal-galactosyltransferase enzyme responsible for
Galα1→ 3Gal synthesis and expression. These mice develop normally and exhibit no gross …
