Molecular basis of egg coat cross-linking sheds light on ZP1-associated female infertility

Glycoprotein ZP1 is a component of the oocyte’s zona pellucida (ZP), and mutations in human ZP1 are linked to female infertility. Here, using structure-function analysis, the authors suggest that filament cross-linking by ZP1 is required to form a stable ZP in human, and infertility mutations interf...

Résumé:Glycoprotein ZP1 is a component of the oocyte’s zona pellucida (ZP), and mutations in human ZP1 are linked to female infertility. Here, using structure-function analysis, the authors suggest that filament cross-linking by ZP1 is required to form a stable ZP in human, and infertility mutations interfere with cross-linking.
