Recombinant Mouse Sperm ZP3-binding Protein (ZP3R/sp56) Forms a High Order Oligomer That Binds Eggs and Inhibits Mouse Fertilization in Vitro
4 Mar 2008
Abstract excerpt
Many candidates have been proposed as zona pellucida-binding proteins. Without precluding a role for any of those candidates, we focused on mouse sperm protein ZP3R/sp56, which is localized in the acrosomal matrix. The objective of this study was to analyze the role of ZP3R/sp56 in mouse fertilization. We expressed recombinant ZP3R/sp56 as a secreted protein in HEK293 cells and purified it from serum-free,...
