Recombinant human zona pellucida protein C expressed in Chinese hamster ovary cells associates to the acrosomal region of human spermatozoa and inhibits sperm-zona pellucida interaction in the hemizona assay. Recombinant ...

In a previous paper we demonstrated that boar β-acrosin recombinant proteins were able to bind non-enzymatically to solubilized pig zona pellucida (ZP) glycoproteins. Here we report the participation of boar β-acrosin in ...

Summary: Gamete interactions in mouse involves at least two steps: the first is the interaction of a spermatozoa receptor located in the plasma membrane and ZP3, a zona pellucida (ZP) glycoprotein. ZP3 also can induce the ...

Sperm-zona pellucida (ZP) binding is a necessary event for successful fertilization. The aim of this study was to determine the effect of trace minerals such as copper (Cu), manganese (Mn), selenium (Se) and zinc (Zn) on ...

ABSTRAC: perm-egg interaction is a complex process mediated by receptors and ligands present  in both gametes, spermatozoon and  oocyte. The important role played by the carbohydrates in the gamete interaction  is well ...

The successful use of assisted reproduction techniques (ART) depends in part on the sperm physiological status. Several sperm selection procedures have been applied to improve quality of sperm population when using the ...

Background information. The egg envelope is an extracellular matrix that surrounds oocytes. In frogs and mammals, a prominent feature of envelope modification following fertilization is the N-terminal proteolysis of the ...
