中心体的异常扩增可能导致染色体分离不当和非整倍体,并与癌症的发展有关。在这里,我们证明了Axin,Wnt信号中的支架蛋白,在有丝分裂过程中被PLK 1磷酸化。Axin Ser-157被PLK 1磷酸化后,Axin与γ-微管蛋白的结合消失,而Ser-157被丙氨酸取代后,Axin与γ-微管蛋白的相互作用持续存在。此外,Axin-S157 A的过表达显著增加了具有多中心体的细胞的数量。这些结果表明,由PLK 1介导的Axin的磷酸化状态动态调节其与γ-微管蛋白和中心体形成和分离的关联。
Abnormal amplification of centrosomes could lead to improper chromosome segregation and aneuploidy and is implicated in cancer development. Here, we demonstrate that Axin, a scaffolding protein in Wnt signaling, is phosphorylated by PLK1 during mitosis. Phosphorylation of Axin Ser-157 by PLK1 abolished Axin association with γ-tubulin, while substitution of Ser-157 with alanine exhibited sustained interaction with γ-tubulin. In addition, overexpression of Axin-S157A significantly increased the number of cells with multi-centrosomes. These results suggest that the phosphorylation status of Axin, mediated by PLK1, dynamically regulates its association with γ-tubulin and centrosome formation and segregation.
