The released hyalin modifies the [[extracellular matrix]] of the fertilized egg to block other sperm from binding to the egg, and is known as the slow-block to [[polyspermy]]. All animals have this slow-block mechanism. ==External links== *[http://www.biochem.northwestern.edu/holmgren/Glossary/Definitions/Def-H/hyalin.html] {{protein-stub}}
