Abstract excerpt
Formation of the egg's extracellular matrix, the zona pellucida, is critical for fertilization and development of growing embryos. Zona pellucida glycoproteins, ZP1, ZP2, and ZP3, are secreted to form an insoluble extracellular matrix surrounding mammalian eggs. All cloned mammalian zona pellucida sequences contain a furin consensus cleavage site, RX(K)/(R)R, upstream of a putative transmembrane domain, which...
