大多数物种的减数分裂纺锤体缺乏中心体,在无中心体减数分裂纺锤体中染色体分离的机制还不清楚。Inc.在elegansocytes中,纺锤体微管依赖于微管稳定蛋白CLS-2CLASP对染色体施加向极力。激酶BUB-1Bub 1和CLS-2CLASP定位于中央纺锤体,并在整个后期显示动态定位模式,但调节其后期特异性定位的信号仍然未知。我们已经表明,SUMO调节BUB-1定位在中期I。在这里,我们发现SUMO修饰BUB-1Bub 1是由SUMO E3连接酶GEI-17和SUMO蛋白酶ULP-1调节。在后期I早期,BUB-1定位于分离的染色体之间需要SUMO,SUMO缺失部分表型模仿BUB-1Bub 1缺失。我们还表明,CLS-2CLASP是SUMO介导的调节。总的来说,我们提供了一种新的,SUMO介导的控制蛋白质动力学在早期后期我在卵母细胞的证据。
Meiotic spindles in most species lack centrosomes and the mechanisms that underlie faithful chromosome segregation in acentrosomal meiotic spindles are not well understood. InC. elegansoocytes, spindle microtubules exert a poleward force on chromosomes dependent on the microtubule-stabilising protein CLS-2CLASP. The kinase BUB-1Bub1and CLS-2CLASPlocalise in the central-spindle and display a dynamic localisation pattern throughout anaphase but the signals regulating their anaphase-specific localisation remains unknown. We have shown that SUMO regulates BUB-1 localisation during metaphase I. Here, we found that SUMO modification of BUB-1Bub1is regulated by the SUMO E3 ligase GEI-17 and the SUMO protease ULP-1. SUMO is required for BUB-1 localisation in between segregating chromosomes during early anaphase I, and SUMO depletion partially phenocopies BUB-1Bub1depletion. We also show that CLS-2CLASPis subject to SUMO-mediated regulation. Over-all, we provide evidence for a novel, SUMO-mediated control of protein dynamics during early anaphase I in oocytes.
