Fertilization triggers a series of preprogrammed events functioning to activate egg metabolism, incorporate the paternal genome, and initiate development. The activity of protein tyrosine kinases during egg activation is required for several steps leading to the first cell division. We now present evidence for an additional protein tyrosine kinase-mediated event that occurs between 30 and 45 min after insemination and is not required until gastrulation, which occurs over 24 hr later.
