Processed zona pellucida sperm-binding protein 2
Zona pellucida glycoprotein 2
zona pellucida glycoprotein ZP2
Zona pellucida protein A
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. ZP2 may act as a secondary sperm receptor.
Belongs to the ZP domain family. ZPA subfamily. Contains 1 ZP domain.
Expressed during the 2-week growth phase of oogenesis, prior to ovulation.
The ZP domain is involved in the polymerization of the ZP proteins to form the zona pellucida.
Proteolytically cleaved before the transmembrane segment to yield the secreted ectodomain incorporated in the zona pellucida. Proteolytically cleaved in the N-terminal part after fertilization, yielding a N-terminal peptide of about 30 kDa which remains covalently attached to the C-terminal peptide via disulfide bond(s). This cleavage may play an important role in the post-fertilization block to polyspermy. O-glycosylated; contains sulfate-substituted glycans.
