General annotation (Comments)

Function	The mammalian zona pellucida, which mediates species-specific sperm binding, induction of the acrosome reaction and prevents post-fertilization polyspermy, is composed of three to four glycoproteins, ZP1, ZP2, ZP3, and ZP4. ZP3 is essential for sperm binding and zona matrix formation.
Subunit structure	Polymers of ZP2 and ZP3 organized into long filaments cross-linked by ZP1 homodimers By similarity.
Subcellular location	Processed zona pellucida sperm-binding protein 3: Secreted › extracellular space › extracellular matrix. Cell membrane; Single-pass type I membrane protein.
Tissue specificity	Oocytes.
Domain	The ZP domain is involved in the polymerization of the ZP proteins to form the zona pellucida.
Post-translational modification	Proteolytically cleaved before the transmembrane segment to yield the secreted ectodomain incorporated in the zona pellucida. N-glycosylated By similarity. O-glycosylated; removal of O-linked glycans may play an important role in the post-fertilization block to polyspermy By similarity.
Sequence similarities	Belongs to the ZP domain family. ZPC subfamily. Contains 1 ZP domain.
