背景 | The Ras family small GTPase Ran is involved in nuclear envelope formation, assembly of the mitotic spindle, and nuclear transport (1,2). TPX2, a target of active Ran (RanGTP), is a microtubule nucleating protein. TPX2 is inactive when bound to nuclear importin-alpha. RanGTP activity disrupts this interaction, relieving inhibition of TPX2 (3). TPX2 binding activates Aurora A kinase and promotes its localization to the mitotic spindle (4,5). DNA damage in mitosis leads to loss of interaction between Aurora A and TPX2 and inactivation of Aurora A kinase (6). TPX2 is highly expressed in pancreatic cancer cells, and knockdown of TPX2 expression in these cells is associated with increased sensitivity to paclitaxel (7).Ras家族小GTP酶Ran参与核被膜形成、有丝分裂纺锤体组装和核运输(1,2)。TPX2,活化Ran(RanGTP)的一个靶标,是一种微管核化蛋白。当结合到核输入因子α时TPX2是失活的。RanGTP的活性破坏了这种相互作用,解除了对TPX2的抑制(3)。TPX2结合激活Aurora A激酶并促进其向有丝分裂纺锤体定位(4,5)。有丝分裂过程中的DNA 损伤导致了Aurora A和TPX2相互作用的缺失以及Aurora A激酶的失活(6)。TPX2在胰腺癌细胞中高表达,敲除TPX2后这些细胞对紫杉醇的敏感性增加(7)。 |
