Reassessing the molecular biology of sperm–egg recognition with mouse genetics
19 Dec 2003
Abstract excerpt
The zona pellucida is an extracellular coat that surrounds mammalian eggs and early embryos. This insoluble matrix separates germ from somatic cells during folliculogenesis and plays critical roles during fertilization and early development. The mouse and human zona pellucida contain three glycoproteins (ZP1 or ZPB, ZP2, ZP3), the primary structures of which have been deduced by molecular cloning. Targeted...
