Rabbit Anti-Zona pellucida glycoprotein 3 antibody
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.
Subcellular Location:
Secreted > extracellular space > extracellular matrix and Cell membrane.
Tissue Specificity:
Oocytes.
Post-translational modifications:
Proteolytically cleaved before the transmembrane segment to yield the secreted ectodomain incorporated in the zona pellucida.
N-glycosylated.
O-glycosylated; removal of O-linked glycans may play an important role in the post-fertilization block to polyspermy.
Similarity:
Belongs to the ZP domain family. ZPC subfamily.
Contains 1 ZP domain.
