Protease activity involvement in the passage of mammalian sperm through the zona pellucida [PDF]
Biological Research, 2011 The interaction between acrosome-reacted sperm and zona pellucida proteins is not yet fully understood. Serine protease acrosin and its zymogen proacrosin have been proposed to fulfill this function due to their capacity to bind zona pellucida ...

Effects of human menopausal gonadotropin on zona pellucida and pregnancy outcomes of ovarian stimulation protocols [PDF]
Iranian Journal of Reproductive Medicine, 2015 Background: Human menopausal gonadotropin (hMG) has contributed many improvements to human assisted reproduction. However, effects of hMG on oocyte development and clinical results remain controversial. Objective: This study was conducted to investigate

ZONA PELLUCIDA GLYCOPROTEINS [PDF]
Annual Review of Biochemistry, 1988 All mammalian eggs are surrounded by a relatively thick extracellular coat, the zona pellucida, that plays vital roles during oogenesis, fertilization, and preimplantation development. The mouse zona pellucida consists of three glycoproteins that are synthesized solely by growing oocytes and assemble into long fibrils that constitute a matrix.

Assembly of the Inner Perivitelline Layer, a Homo log of the Mammalian Zona Pellucida: An Immunohistochemical and Ultrastructural Study [PDF]
, 2011 The avian inner perivitelline layer (IPVL), a homologous structure to the mammalian zona pellucida, is deposited between the granulosa cells and the oocyte cell membrane during folliculogenesis. The glycoprotein meshwork of the IPVL forms a 3-dimensional

Protein-carbohydrate interactions during fertilization [PDF]
, 1998 Interaction between gametes during fertilization is at least in part regulated by carbohydrate moieties of the zona pellucida (ZP) and carbohydrate binding proteins of the sperm surface. This review focuses on the protein-carbohydrate interactions during
