Unsourced material may be challenged and removed. 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.
What does MPF stand for in cell cycle?
Maturation promoting factor
Maturation promoting factor (MPF) is a cell cycle checkpoint that regulates the passage of a cell from the G2 growth phase to the M phase. It is also known as the G2 checkpoint, and ensures that DNA replication during the S phase did not produce any mistakes.
What is MPF in medical?
Medical Definition of maturation promoting factor : a protein complex that in its active form causes eukaryotic cells to undergo mitosis —abbreviation MPF.
What does maturation promoting factor do?
Maturation-promoting factor (MPF) is a cell cycle control element able to cause metaphase when injected into amphibian oocytes or when incubated with nuclei in a cell-free system.
What two proteins make up mitosis promoting factor?
MPF is made up of two proteins, a protein kinase (cdc2 in yeast) whose levels are constant throughout the cell cycle and a cyclin (cdc 13 in yeast) whose levels fluctuate during the cell cycle.
What happens to MPF after mitosis?
What happens to MPF during mitosis? Cyclin is degraded; the concentration of cyclin-dependent kinase remains unchanged, but without cyclin, MPF is not formed. Cyclin is degraded; the concentration of cyclin-dependent kinase remains unchanged, but without cyclin, MPF is not formed.
What happens when MPF cyclin levels are highest?
(MITOSIS PROMOTING FACTOR) MPF is a cyclin-CDK complex which acts at the G2 checkpoint which triggers the cells undergo mitosis. (MPF activity corresponds to high levels of cyclin it is active when cyclin concentration is high. which ensures that daughter cells do not end up with missing or extra chromosomes.
What is MPF and its function?
The primary function of MPF is to promote spindle assembly, chromatin condensation and the breakdown of the nuclear envelope.

What are the three parts of the maturation promoting factor?
With this in mind, identify the three parts of the maturation promoting factor (MPF). the MPF is made from a kinase, a cyclin, and a phosphate group.
