Although it is possible to exit CSF mediated MetII arrest by inhibiting the CDK1 component of MPF [ 21, 22 ], physiologically a sperm Ca 2+ signal induces loss of cyclin B rather than CDK1 … Nettet5. mai 1998 · Although CSF prevents the degradation of cyclin, the inactivation of CSF itself is not required for the proteolysis of the cyclin subunit of MPF and for the resulting exit from meiotic metaphase.

NettetUnlike MPF, CSF has long resisted detailed biochemical characterization or purification, and defining its molecular composition has been difficult (Shibuya and Masui, 1988).
