Cell division is a highly regulated process that secures the generation of healthy progeny in all organisms, from yeast to human. Dysregulation of this process can lead to uncontrolled cell proliferation and genomic instability, both which are hallmarks of cancer. Cell cycle progression is dictated by a complex network of kinases and phosphatases. These enzymes act on their substrates in a highly specific temporal manner ensuring that the process of cell division is unidirectional and irreversible. Key events of the cell cycle, such as duplication of genetic material and its redistribution to daughter cells, occur in S-phase and mitosis, respectively. Deciphering the dynamics of phosphorylation/dephosphorylation events during these cell cycle phases is important. Here, we showcase a quantitative proteomic and phosphoproteomic mass spectrometry dataset that profiles both early and late phosphorylation events and associated proteome alterations that occur during S-phase and mitotic arrest in the model organism . This dataset is of broad interest as the molecular mechanisms governing cell cycle progression are conserved throughout evolution. The data has been deposited in ProteomeXchange with the dataset identifier PXD037291.
细胞分裂是一个受到高度调控的过程,确保了从酵母到人类等所有生物体中健康后代的产生。这一过程的失调会导致细胞不受控制地增殖和基因组不稳定,而这两者都是癌症的标志。细胞周期的进程由激酶和磷酸酶的复杂网络决定。这些酶以高度特定的时间方式作用于它们的底物,确保细胞分裂过程是单向且不可逆的。细胞周期的关键事件,如遗传物质的复制及其向子细胞的重新分配,分别发生在S期和有丝分裂期。解读这些细胞周期阶段中磷酸化/去磷酸化事件的动态变化很重要。在这里,我们展示了一个定量蛋白质组学和磷酸蛋白质组学质谱数据集,该数据集描绘了在模式生物的S期和有丝分裂停滞期间发生的早期和晚期磷酸化事件以及相关的蛋白质组改变。由于控制细胞周期进程的分子机制在整个进化过程中是保守的,所以该数据集具有广泛的研究意义。数据已存入ProteomeXchange,数据集标识符为PXD037291。
