Previous GeneCards Identifiers for ZP2 Gene
The zona pellucida is an extracellular matrix that surrounds the oocyte and early embryo. It is composed of three glycoproteins with various functions during fertilization and preimplantation development. The glycosylated mature peptide is one of the structural components of the zona pellucida and functions in secondary binding and penetration of acrosome-reacted spermatozoa. Female mice lacking this gene do not form a stable zona matrix and are sterile. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2014]
GeneCards Summary for ZP2 Gene
ZP2 (Zona Pellucida Glycoprotein 2) is a Protein Coding gene. Diseases associated with ZP2 include Infertility and Acheiropody. Among its related pathways are Fertilization and Ovarian Infertility Genes. GO annotations related to this gene include coreceptor activity and acrosin binding. An important paralog of this gene is ZP4.
UniProtKB/Swiss-Prot for ZP2 Gene
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. ZP2 may act as a secondary sperm receptor.
