Zona Pellucida Binding Protein 2 (ZPBP2) is a sperm-specific protein crucial for male fertility. It belongs to the zona pellucida-binding protein family and is primarily localized in the acrosomal matrix of spermatozoa. Structurally, ZPBP2 contains conserved ZP-binding domains that facilitate interactions with glycoproteins of the zona pellucida, the extracellular matrix surrounding oocytes. This interaction is vital for sperm-egg recognition and adhesion during fertilization. Studies highlight its role in sperm head shaping, acrosome formation, and the regulation of acrosomal enzymes required for penetrating the zona pellucida. Dysfunction or mutations in ZPBP2 are linked to teratozoospermia, particularly globozoospermia—a condition characterized by round-headed sperm lacking functional acrosomes, leading to infertility. Recombinant human ZPBP2 protein is typically expressed in eukaryotic systems (e.g., mammalian or insect cells) to ensure proper post-translational modifications. It serves as a critical tool for studying sperm biology, protein-protein interactions in fertilization, and developing diagnostic assays for male infertility. Ongoing research also explores its potential as a therapeutic target or biomarker for reproductive disorders. Despite its established role in spermatogenesis, further investigations are needed to elucidate its molecular mechanisms and broader physiological implications.
