  • Search this entire website. Enter identifiers, names or keywords for genes, diseases, strains, ontology terms, etc. (e.g. Pax6, Parkinson, ataxia)
  • Use OR to search for either of two terms (e.g. OR mus) or quotation marks to search for phrases (e.g. "dna binding").
  • Boolean search syntax is supported: e.g. Balb* for partial matches or mus AND NOT embryo to exclude a term

Protein Domain
Type: Domain
Description: The zona pellucida (ZP) domain is a protein polymerisation module of ~260amino acid module, which is found at the C terminus of many secretedeukaryotic glycoproteins that play fundamental roles in development, hearing,immunity, and cancer [, , , ].Proteins containing a ZP domain include:Sperm receptor proteins ZP2 and ZP3. Along with protein ZP1, proteins ZP2and ZP3 are responsible for sperm-adhesion to the zona pellucida. ZP3 firstbinds to specific sperm proteins, thus mediating sperm contacts with theoocyte. ZP2 acts as a second sperm receptor reinforcing the interactions.ZP1 cross-links the polymers formed by ZP2 and ZP3.Zona pellucida sperm-binding protein B (ZP-B) (also known as ZP-X in rabbitand ZP-3 alpha in pig).Glycoprotein GP2, the major component of pancreatic secretory granulemembranes.TGF-beta receptor type III (also known as betaglycan). This protein is aproteoglycan that binds to TGF-beta and could be involved in capturing andretaining TGF-beta for presentation to the signalling receptors.Uromodulin (also known as Tamm-Horsfall urinary glycoprotein). The functionof this protein, which is the most abundant in human urine, is not yetclear.Chicken beta-tectorin, a major glycoprotein of avian tectorial membrane.Most ZP domain proteins are synthesized as precursors with carboxy-terminaltransmembrane domains or glycosyl phosphatidylinositol (GPI) anchors [].The ZP domain contains eight strictly conserved cysteines, which formdisulphide bridges. The disulphide bonds within the ZP domains are divided intotwo groups, suggesting that the ZP domain consists of two subdomains. Inaddition to the conserved cysteines, only a few aromatic or hydrophobic aminoacids are absolutely invariant, probably as a result of structural rather thanfunctional constraints [, , ].
