CC -!- FUNCTION: Component of the zona pellucida, an extracellular matrix
CC surrounding oocytes which mediates sperm binding, induction of the
CC acrosome reaction and prevents post-fertilization polyspermy. The zona
CC pellucida is composed of 3 to 4 glycoproteins, ZP1, ZP2, ZP3, and ZP4.
CC ZP4 may act as a sperm receptor. {ECO:0000256|ARBA:ARBA00037545}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000256|ARBA:ARBA00004251};
CC Single-pass type I membrane protein {ECO:0000256|ARBA:ARBA00004251}.
CC Membrane {ECO:0000256|ARBA:ARBA00004479}; Single-pass type I membrane
CC protein {ECO:0000256|ARBA:ARBA00004479}. Zona pellucida
CC {ECO:0000256|ARBA:ARBA00024183}.
CC -!- SIMILARITY: Belongs to the ZP domain family. ZPB subfamily.
CC {ECO:0000256|ARBA:ARBA00010863}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|PROSITE-ProRule:PRU00779}.
