Cyclin , mitotic

APC is active from mid-M phase (anaphase) to the end of G1 phase and required for disconnecting sister chromatids and exit from M-Phase to Gl. The complex mediates the ubiquitination of Securin and Cyclin B. Degradation of these proteins, which block mitotic progression, promotes anaphase onset and exit from mitosis. [Pg.1265]

Based on the functional analysis of Cdkl and Cdk2 complexes, we have proposed a model for the conversion of the mitotic cell cycle into an endoreduplication cycle (Fig. 1A Edgar Lehner 1996). Accordingly, this cell cycle conversion is dependent on elimination of Cdkl activity and periodic activation of cyclin E/Cdk2. Cyclin E is required for endocycles and a pulse of ectopic cyclin E expression is sufficient to trigger endoreduplication. Cdk2... [Pg.45]

In a recent study, LNCaP and PC3 prostate cancer cells treated with lycopene-based agents have been reported to undergo mitotic arrest. Lycopene s antiproliferative effects were likely achieved through a block in Gl/S transition mediated by decreased levels of cyclins D1 and E and cyclin-dependent kinase4 and suppressed retinoblastoma phosphorylation (Ivanov et al., 2007). [Pg.473]

In yeast, the MAP kinase Fus3 induces cell cycle arrest via the degradation of cyclins, Clnl and Cln2. The mitotic cyclins (CYCLIN) are cell cycle proteins that bind the protein kinase Cdc2 during interphase... [Pg.225]

Also identified during the mid-1990s was the APC (anaphase promoting complex - also known as the cyclosome), another multi-subunit cullin-containing E3 that mediates ubiquitylation of mitotic cyclins [18, 19]. Mdm2, initially thought to be a HECT domain variant, was shown in 1997 to have E3 activity towards p53 in vitro [20]. For the non-HECT E3s no common structural feature had been detected. Thus, by 1997 the only defined molecular signature for E3 activity was the HECT domain. [Pg.45]
