...Enrico Maria Daldello; Xuan G. Luong; Cai-Rong Yang; Jonathan Kuhn; Marco Conti ABSTRACT Cyclins associate with cyclin-dependent serine/threonine kinase 1 (CDK1) to generate the M phase-promoting factor (MPF) activity essential for progression through mitosis and meiosis. Although cyclin B1 (CCNB1...

... cascade, for conversion of inactive pre-MPF into active MPF. We have found that Myt1 is likely to be the Mos target in this process, as Mos interacts with Myt1 in oocyte extracts and Mos triggers Myt1 phosphorylation on some sites in vivo, even in the absence of MAPK activation. We propose that Mos...

... the downstream targets of activated PKA remain unknown, neither the synthesis of new proteins nor the activation of MAPKs (mitogen-activated protein kinases) appeared to be required for GVBD after 5-HT stimulation.

A transient and low-level early activation of MAP kinase increases the efficiency of cell cycle activation later on, when MAP kinase...

...Alex McDougall; Mark Levasseur ABSTRACT We have investigated the relationship between the sperm-triggered Ca 2+ oscillations and the activities of two cell cycle kinases (MPF activity and MAP kinase activity) at fertilisation of Ascidiella aspersa oocytes.

Biochemical characterization of Maturation Promoting Factor (MPF) in ascidian oocytes led to the identification of a Cdc2-like kinase activity. Using p13 suc1 -sepharose as a reagent to precipitate the MPF complex, a 67 kDa (67×10 3 M r...

Neither assembly and organization, nor disassembly of the cortical microtubules coincided with MPF activation during mitosis.

In addition, the effects on the MV pattern of the maturation or mitosis promoting factor (MPF) were tested.

The active component of MPF is now known to be the p34 cdc2 protein kinase originally found in yeast. The p34 cdc2 protein kinase displays a characteristic M...
