POST-TRANSLATIONAL MODIFICATION AND INTERACTING PROTEINS OF CENP-E

该子项目是利用 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得主要资金， 因此可以在其他CRISP条目中表示。列出的机构是 中心，不一定是研究者的机构。 细胞周期的进程在多个检查点受到调节。 例如，纺锤体检查点监测染色体分离的保真度。 这个检查点抑制细胞进入后期，直到所有的姐妹染色单体都正确地附着在有丝分裂纺锤体上并在中期板上对齐。 许多蛋白质已被证明在这个过程中是重要的，包括MAD 1，MAD 2，TTK，Bub 1，BubR 1和BubR 2。 先前的研究表明，驱动蛋白相关的运动蛋白CENP-E与BubR 1和TTK相互作用。 为了进一步了解CENP-E对纺锤体检查点的重要性，将采用质谱技术研究CENP-E的相互作用伴侣及其翻译后修饰。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Progression through the cell cycle is regulated at multiple checkpoints. For example, the spindle checkpoint monitors the fidelity of chromosome segregation. This checkpoint inhibits cells from progressing into anaphase until all sister chromatids are properly attached to the mitotic spindle and aligned at the metaphase plate. A number of proteins have been shown to be important in this process including MAD1, MAD2, TTK, Bub1, BubR1 and BubR2. Previous studies have shown that the kinesin-related motor protein CENP-E interacts with BubR1 and TTK. To further understand the importance of CENP-E to the spindle checkpoint mass spectrometry will be used to interaction partners of CENP-E and it post-translational modifications.
