Maturation-promoting factor (abbreviated MPF, also called mitosis-promoting factor or M-Phase-promoting factor) is the cyclin-Cdk complex that was discovered first in frog eggs. It stimulates the mitotic and meiotic phases of the cell cycle.
Is cyclin A component of MPF?
Highly purified maturation-promoting factor (MPF) from Xenopus eggs contains both cyclin B1 and cyclin B2 as shown by Western blotting and immunoprecipitation using Xenopus anti-B-type cyclin antibodies. … These data indicate that B-type cyclin is the other component of MPF besides p34cdc2.
Which cyclin is in MPF?
MPF is a heterodimer, composed of a catalytic CDK1 (p34cdc2) subunit and a regulatory cyclin B subunit. There are at least three types of cyclin B (B1, B2 and B3), and in mammals it appears that cyclin B1 is primarily responsible for MPF activity.
