Mouse Zp3 ELISA Kit (V2LY-0626-LY3221)

zona pellucida sperm-binding protein 3

Component of the zona pellucida, an extracellular matrix surrounding oocytes which mediates sperm binding, induction of the acrosome reaction and prevents post-fertilization polyspermy. The zona pellucida is composed of 3 to 4 glycoproteins, ZP1, ZP2, ZP3, and ZP4. ZP3 is essential for sperm binding and zona matrix formation.

Oocyte maturation defect 3 (OOMD3):
An autosomal dominant infertility disorder characterized by abnormal oocytes that lack the zona pellucida, and oocytes degeneration.

Extracellular: 23-387
Helical: 388-408
Cytoplasmic: 409-424

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.
