Assessing Ovastacin and Fetuin B as a Non-Hormonal Contraceptive Targets
Background: Ovastacin is an oocyte-specific protease involved in sperm adhesion and fertilization. Research into the ovastacin’s protease function suggest it acts on the post-fertilization cleavage of ZP2 via cortical granule exocytosis1. Cleaved ZP2 then causes hardening of the zona pellucida and is then unable to support further sperm binding2. Zona pellucida regulation is critical for Read More …
