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; N-linked glycans are of high mannose/hybrid type, as well as bi-, tri- and tetra-antennary complex types.

O-glycosylated; removal of O-linked glycans may play an important role in the post-fertilization block to polyspermy.

Sequence similarities

Belongs to the ZP domain family. ZPC subfamily.

Contains 1 ZP domain.
