To achieve fertilization, sperm and egg are equipped with specific molecules which mediate
the steps of gamete interaction. In mammals, the first interaction between sperm and egg …

The sperm protein fertilin (also known as PH-30) is a candidate for mediating the
interactions between sperm and egg plasma membranes. Fertilin is a heterodimer. The β …

The acrosome reaction is a prerequisite for zona pellucida penetration by mammalian
spermatozoa. In some species, the sperm undergo the acrosome reaction before binding to …

The mouse egg zona pellucida (ZP) is composed of three glycoproteins, called mZP1− 3.
Disruption of the mZP3 gene by targeted mutagenesis yields mice that are homozygous …

A predominant glycoprotein in the vitelline envelope (VE) of the anuran Xenopus laevis is
gp41, known to be proteolytically converted from gp43 of the coelomic egg envelope …

Despite the economical importance of in vitro gamete technologies in cattle, only little is
known about the molecular mechanisms of binding of spermatozoa to the zona pellucida …

To investigate the involvement of protein kinases in signal transduction in the human zona
pellucida (ZP)-induced acrosome reaction (AR), the effects of protein kinase (PK) activators …

Oligosaccharide side chains of zona pellucida (ZP) glycoproteins play a key role in the
sperm-egg interaction phenomena during fertilization. In the present study, modifications of …

The mammalian zona pellucida contains several glycoproteins whose oligosaccharide
moieties are known to play a key role in the interaction with spermatozoa. Since zona …

In this study we investigated the ultrastructure of macaque sperm induced to acrosome-react
with calcium ionophore A23187, and the interaction between these acrosome-reacted …
