Abstract:
Human zona pellucida (hZP) plays a critical role in the recognition, binding of sperms and oocytes, induction of acrosomal exocytosis, and avoidance of polyspermy. Human ZP is composed of four glycoproteins designated as hZP1, hZP2, hZP3 and hZP4. This paper reviews the actions of native hZP or recombinant hZP on acrosomal exocytosis and sperm-ZP binding.
