title: The role of cyclin synthesis and degradation in the control of maturation promoting factor activity.
abstract: We show that cyclin plays a pivotal role in the control of mitosis. A proteolysis-resistant mutant of cyclin prevents the inactivation of maturation promoting factor and the exit from mitosis both in vivo and in vitro. We have used a fractionated extract to study the activation of MPF by added cyclin protein.
