Protein Structure
UniProt Annotation
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. ZP2 may act as a secondary sperm receptor.
Subcellular Localization Processed zona pellucida sperm-binding protein 2: Secreted, extracellular space, extracellular matrix. Note=The glycoproteinaceous translucent extracellular matrix that surrounds the mammalian oocyte is called zona pellucida.Cell membrane; Single-pass type I membrane protein.
Disease Associations
Tissue Specificity Oocytes.
