Zona pellucida binding protein 1 (ZPBP1), a spermatid and spermatozoon protein that
localizes to the acrosome, was originally identified in pigs and named for its binding to the …

Despite years of research work, biologists remain divided over the issue of zona pellucida
function during fertilization and the mode of sperm-ZP penetration. The present review …

A translucent matrix termed the zona pellucida (ZP) surrounds the mammalian oocyte. It
plays a critical role in fertilization by acting as a" docking site" for binding of spermatozoa …

The extracellular matrix surrounding avian oocytes, called the perivitelline membrane (PL),
consists of at least two major glycoproteins, ZP3 and ZP1. Our previous study using …

The acrosome reaction of newt sperm is induced at the surface of egg jelly and the
acrosome‐reacted sperm acquire the ability to bind to the vitelline envelope. However …

The zona pellucida is an extracellular matrix surrounding growing oocytes, ovulated eggs
and preimplantation embryos. In mice, the zona pellucida is composed of three …

Among all of the sperm acrosomal trypsin-like proteinases studied, acrosin (EC 3.4. 21.10)
