Zona pellucida-like domain (ZP domain / ZP-like domain) is a family of evolutionarily related proteins.^[1][2]

A large domain, containing around 260 amino acids, has been recognised in a variety of receptor-like eukaryotic glycoproteins.^[1] All of these proteins are mosaic proteins composed of various domains and that all have a large extracellular region, often followed by either a transmembrane region and a very short cytoplasmic region or by a GPI-anchor. The domain common to all these proteins is a bipartite protein polymerization module ^[3][4] that is located in the C-terminal portion of the extracellular region and contains 8 or 10 conserved Cys residues involved in disulfide bonds. ^[5][6]

Examples

Humans genes encoding proteins containing this domain include:

• CUZD1
• DMBT1
• ENG
• GP2
• OIT3
• POMZP3
• TECTA, TECTB, TGFBR3
• UMOD, UMODL1
• ZP1, ZP2, ZP3, ZP4, ZPLD1
