有丝分裂纺锤体的位置由皮质分子马达与星形微管的相互作用控制。在动物细胞中,Inscuteable(Pins)的伴侣在大脑皮层协调Dynein和Kinesin-73(哺乳动物中的Khc73;KIF13B)的活性来定位纺锤体。虽然这两个马达的运动方向相反,但它们的协同作用对于销钉介导的主轴定向是必要的。在这里,我们确定了Dynein和Khc73之间的物理联系,它调节了合作的主轴定位。KHC73的S马达和MBS结构域将PIN连接到微管+末端,而其柄结构域是Dynein激活和纺锤体精确定位所必需的。茎结构域中的基序以磷酸依赖的方式结合14-3-3ζ,14-3-3ε与14-3-3 DNA二聚化。14-3-3ζ/ε异源二聚体与Dynein适配器裸体结合,完成Dynein连接。Khc73 Styk/14-3-3/nude通路定义了一种物理连接,它协调多个马达蛋白的活动来精确定位纺锤体。
Mitotic spindle position is controlled by interactions of cortical molecular motors with astral microtubules. In animal cells, Partner of Inscuteable (Pins) acts at the cortex to coordinate the activity of Dynein and Kinesin-73 (Khc73; Kif13B in mammals) to orient the spindle. Though the two motors move in opposite directions, their synergistic activity is required for robust Pins-mediated spindle orientation. Here we identify a physical connection between Dynein and Khc73 that mediates cooperative spindle positioning. Khc73’s motor and MBS domains link Pins to microtubule plus ends, while its stalk domain is necessary for Dynein activation and precise positioning of the spindle. A motif in the stalk domain binds, in a phospho-dependent manner, 14-3-3ζ, which dimerizes with 14-3-3ε. The 14-3-3ζ/ε heterodimer binds the Dynein adapter NudE to complete the Dynein connection. The Khc73 stalk/14-3-3/NudE pathway defines a physical connection that coordinates the activities of multiple motor proteins to precisely position the spindle.
