Egg activation: Upstream of the fertilization calcium signal
1 Jul 2000
Abstract excerpt
Interaction of sperm and egg at fertilization induces well-coordinated molecular events including specific recognition between species, adhesion and fusion, that lead to the formation of a zygote, a totipotent cell that develops into a new individual. A calcium signal, common to a great number of species, from marine invertebrates to mammals, is essential to activate the metabolism of the unfertilized oocyte....
