Research AreasDevelopmental Biology

Function

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.

Biological Context

Subcellular Location: Cell membrane (Single-pass type I membrane protein)
Tissue Specificity: Expressed in oocytes (at protein level)
Disease Association: Oocyte/zygote/embryo maturation arrest 3 (OZEMA3) : An autosomal dominant infertility disorder characterized by abnormal oocytes that lack the zona pellucida, and oocytes degeneration. [The disease is caused by variants affecting the gene represented in this entry]

Product Specifications
