Round‐Headed Spermatozoa: A Model to study the Role of the Acrosome in early events of Gamete Interaction: Rundkopfspermatozoen: Ein Modell zum Studium der Rolle des Akrosoms
(1990)
Summary: Gamete interactions in mouse involves at least two steps: the first is the interaction of a spermatozoa receptor located in the plasma membrane and ZP3, a zona pellucida (ZP) glycoprotein. ZP3 also can induce the ...
S100 A9 is expressed and secreted by the oviduct epithelium, interacts with gametes and affects parameters of human sperm capacitation in vitro
(Wiley, 2019-10)
Our previous findings demonstrate that some oviductal secretion proteins bind to gametes and affect sperm physiology and gamete interaction. One of these proteins possesses an estimated molecular weight of 14 kDa. The ...
A scanning electron microscopy study of frozen thawed dog sperm during in vitro gamete interaction
(WILEY-BLACKWELL PUBLISHING, INC, 2009)
Evidence that human epididymal protein ARP plays a role in gamete fusion through complementary sites on the surface of the human egg
(Society for the Study of Reproduction, 2001-05)
Human epididymal sperm protein ARP, a member of the cysteine-rich secretory proteins (CRISP) family, exhibits significant homology with rat epididymal protein DE, a candidate molecule for mediating sperm-egg fusion in ...
Characterization of the functional domains of boar acrosin involved in nonenzymatic binding to homologous zona pellucida glycoproteins
(1998)
During the first steps of the gamete interaction, the proacrosin/acrosin system seems to play a crucial role in the secondary binding, holding acrosome-reacted spermatozoa during their passage through the zona pellucida. ...
Epithelial and neural cadherin expression in the mammalain reproductive tract and gametes and their participation in fertilization-related events
(Academic Press Inc Elsevier Science, 2015-05)
Mammalian fertilization involves a series of well-orchestrated cell-cell interaction steps between gametes, as well as among spermatozoa and somatic cells of both the male and female reproductive tracts. Cadherins are ...
Molecular mechanisms involved in gamete interaction: evidence for the participation of cysteine-rich secretory proteins (CRISP) in sperm-egg fusion
(Nottingham University Press, 2007)
Epididymal protein DE and testicular protein Tpx-1 are two cysteine-rich secretory proteins also known as CRISP-1 and CRISP-2, respectively. DE/CRISP-1 is localised on the equatorial segment of acrosome-reacted sperm and ...
Cysteine-rich secretory proteins (CRISP) proteins are key players for mammalian fertilization and fertility
(Frontiers Media, 2021)
Mammalian fertilization is a complex process involving a series of successive sperm-egg interaction steps mediated by different molecules and mechanisms. Studies carried out during the past 30 years, using a group of ...
