Post Translational Modifications | Proteolytically cleaved before the transmembrane segment to yield the secreted ectodomain incorporated in the zona pellucida. N-glycosylated. O-glycosylated.removal of O-linked glycans may play an important role in the post-fertilization block to polyspermy. |
Function | Component of the zona pellucida, an extracellular matrix surrounding oocytes which mediates sperm binding, induction of the acrosome reaction and prevents post-fertilization polyspermy. The zona pellucida is composed of 3 to 4 glycoproteins, ZP1, ZP2, ZP3, and ZP4. ZP3 is essential for sperm binding and zona matrix formation. |
