- The physiological function of Sentrin/SUMO-specific proteases (SENPs) remains largely unexplored, and little is known about the regulation of SENPs themselves. Here, we show that a modest increase of reactive oxygen spec...
- ZIP: a novel transcription repressor, represses EGFR oncogene and suppresses breast carcinogenesis
[作者:Li, RF; Zhang, H; Yu, WH; Chen, YP; Gui, B; Liang, J; Wang, Y; Sun, LY; Yang, XH; Zhang, Y; Shi, L; Li, YY; Shang, YF,期刊:EMBO journal, 页码:2763-2776 , 文章类型: Article,,卷期:2009年28-18]
- Despite the importance of epidermal growth factor receptor (EGFR) in animal development and malignant transformation, surprisingly little is known about the regulation of its expression. Here, we report a novel zinc fing...
- Regulated activity of PP2A-B55 delta is crucial for controlling entry into and exit from mitosis in Xenopus egg extracts
[作者:Mochida, S; Ikeo, S; Gannon, J; Hunt, T,期刊:EMBO journal, 页码:2777-2785 , 文章类型: Article,,卷期:2009年28-18]
- Entry into mitosis depends on the activity of cyclin-dependent kinases (CDKs). Conversely, exit from mitosis occurs when mitotic cyclins are degraded, thereby extinguishing CDK activity. Exit from mitosis must also requi...
- Greatwall maintains mitosis through regulation of PP2A
[作者:Vigneron, S; Brioudes, E; Burgess, A; Labbe, JC; Lorca, T; Castro, A,期刊:EMBO journal, 页码:2786-2793 , 文章类型: Article,,卷期:2009年28-18]
- Greatwall (GW) is a new kinase that has an important function in the activation and the maintenance of cyclin B-Cdc2 activity. Although the mechanism by which it induces this effect is unknown, it has been suggested that...
- Proofreading dynamics of a processive DNA polymerase
[作者:Ibarra, B; Chemla, YR; Plyasunov, S; Smith, SB; Lazaro, JM; Salas, M; Bustamante, C,期刊:EMBO journal, 页码:2794-2802 , 文章类型: Article,,卷期:2009年28-18]
- Replicative DNA polymerases present an intrinsic proofreading activity during which the DNA primer chain is transferred between the polymerization and exonuclease sites of the protein. The dynamics of this primer transfe...
- A non-canonical function of topoisomerase II in disentangling dysfunctional telomeres
[作者:Germe, T; Miller, K; Cooper, JP,期刊:EMBO journal, 页码:2803-2811 , 文章类型: Article,,卷期:2009年28-18]
- The decatenation activity of topoisomerase II (Top2), which is widely conserved within the eukaryotic domain, is essential for chromosomal segregation in mitosis. It is less clear, however, whether Top2 performs the same...
