细胞周期检查点(Cell cycle checkpoints)是为了确保细胞在复制过程中的完整性和保真度。真核生物存在四个重要的细胞检查点,分别为G1/S Checkpoint,Intra-S checkpoint,G2/M checkpoint,Spindle assembly checkpoint(SAC)。 G1/S Checkpoint 在生长因子的刺激下,细胞从休眠状态中脱离并进入G1期。这些刺激驱动细胞通过...
S 期延伸至所有的 DNA 都被复制完毕;从S期末直至有丝分裂称为G2期,在此期间细胞有两套完整的二倍体染色体。 细胞周期检查点(Cell cycle checkpoints)是为了确保细胞在复制过程中的完整性和保真度。真核生物存在四个重要的细胞检查点,分别为G1/S Checkpoint,Intra-S checkpoint,G2/M checkpoint,Spindle assembly...

细胞周期细胞周期检查点 (checkpoint)是细胞周期(cell cycle)中的一套保证DNA复制和染色体(chromosome)分配质量的检查机制,是一类负反馈调节机制.当细胞周期进程中出现异常事件,如DNA损伤或DNA复制受阻时,这类调节机制就被激活,及时地中断细胞周期的运行.待细胞修复或排除故障后,细胞周期才能恢复运转.图1所示为细胞周期...

Positive Regulation of the Cell Cycle Two groups of proteins, called cyclins and cyclin-dependent kinases (Cdks), are responsible for the progress of the cell through the various checkpoints. The levels of the four cyclin proteins fluctuate throughout the cell cycle in a predictable pattern (Fig...
