Fertilization is defined as the process of union of two gametes, eggs and sperm. When
mammalian eggs and sperm come into contact in the female oviduct, a series of steps is set …

Gamete recognition has been studied extensively in the mouse. In this system, it is generally
believed that sperm bind to a class of O-linked oligosaccharides on the zona pellucida …

The mouse zona pellucida glycoprotein, mZP2, is thought to be the secondary receptor on
eggs for retention of acrosome-reacted sperm during fertilization. Here, we present evidence …

The proteins of fish egg envelopes are encoded by genes that are closely related to the
genes for human zona pellucida proteins. A cluster of three genes coding for an egg …

Recent results from our laboratory have revealed the role of sulfogalactosylglycerolipid
(SGG) in mouse sperm‐zona pellucida (ZP) binding. In this report, we demonstrated the …

The Xenopus laevis egg envelope is composed of six or more glycoproteins, three of which
have been cloned and identified as the mammalian homologs ZPA (ZP2), ZPB (ZP1) and …

Purified mouse sperm receptor, a zona pellucida glycoprotein called mZP3, binds to plasma
membrane overlying acrosome-intact sperm heads (PM Wassarman, 1999, Cell 96, 175 …

The zona pellucida of mammalian oocytes plays an important role in binding and activation
of sperm cells during the molecular events leading to fertilization. The genes coding for the …

Sperm with a large acrosome such as that of guinea pigs and hamsters have a subdomain
structure in the anterior acrosome, but the mouse acrosome looks homogeneous and its …

Bonnet monkey (Macaca radiata) zona pellucida glycoprotein-B (bmZPB), excluding the N-
terminal signal sequence and the C-terminus transmembrane-like domain, has been …
