Summary

As the amphibian oocyte becomes the fertilisation-competent egg an actin-myosin assembles in the cortex which provides for the cortical contraction that accompanies the fertilisation. A number of recent investigations provide data for development of a model detailing the structural changes which should accompany the development of this contractile network as well as the signalling mechanisms which regular assembly and contraction.
