This entry represents an immunoglobulin-like domain found in the N-terminal region of Zona pellucida sperm-binding proteins 1 and 4 (ZP1 and ZP4) [1]. ZP1 and ZP4 are components of the zona pellucida, an extracellular matrix surrounding oocytes which mediates sperm binding, induction of the acrosome reaction and prevents post-fertilization polyspermy [2].
