多个有丝分裂激动素和微管相关蛋白(MAP)协同作用,指导细胞质分裂(Glotzer,M.2005)。科学。307:1735-1739)。在后期细胞中,这些蛋白质中的许多与被称为中央纺锤体的反平行微管阵列相关联。MAP和微管捆绑蛋白PRC1(蛋白质调节胞质分裂1)是这种结构完整性所需的关键分子之一(酱,W.,G.Jimenez,N.J.Wells,T.J.Hope,G.M.Wahl,T.Hunter和R.Fukunaga)。1998年。摩尔。牢房。2:877-885;Mollinari,C.,J.P.Kleman,W.酱,G.Schoehn,T.Hunter,和R.L.MarGolis。2002年。J.细胞生物学。157:1175-1186)。在这项研究中,我们确定了内源性PRC1与以前未描述的KIF14蛋白以及其他在细胞质分裂中具有已知功能的有丝分裂蛋白(MKlp1/CHO1、MKlp2和KIf4)之间的相互作用(Hill,E.,M.Clarke和F.A.Barr)。2000年。EMBO J.19:5711-5719;Matuliene,J.,和R.栗山。2002年。摩尔。比奥尔。牢房。1832-1845年;仓泽,Y.,W.C.恩肖,Y.Mochizuki,N.Dohmae和K.Todokoro。2004年。EMBO J.23:3237-3248)。我们发现KIF14通过与PRC1的相互作用靶向中央纺锤体,并且在胞质分裂中具有重要的功能。在KIF14缺失的细胞中,中心纺锤体和卵裂沟的其他成分不能定位,而柠檬酸激酶却不能定位。此外,KIF14和柠檬酸激酶在中心纺锤体和中体的定位是相互依赖的,它们形成的复合体取决于柠檬酸激酶的激活状态。与以前的研究相反(Di Cinto,F.,S.Imarisio,E.Hirsch,V.Broccoli,A.Bulfone,A.Migheli,C.Atzori,E.Turco,R.Triolo,G.P.Dotto,等)。2000年。神经元。28:115-127),我们发现人类细胞分裂对柠檬酸激酶的普遍需求。总之,这些发现确定了有效的细胞质分裂所需的一条新途径。
Multiple mitotic kinesins and microtubule-associated proteins (MAPs) act in concert to direct cytokinesis (Glotzer, M. 2005. Science. 307:1735–1739). In anaphase cells, many of these proteins associate with an antiparallel array of microtubules termed the central spindle. The MAP and microtubule-bundling protein PRC1 (protein-regulating cytokinesis 1) is one of the key molecules required for the integrity of this structure (Jiang, W., G. Jimenez, N.J. Wells, T.J. Hope, G.M. Wahl, T. Hunter, and R. Fukunaga. 1998. Mol. Cell. 2:877–885; Mollinari, C., J.P. Kleman, W. Jiang, G. Schoehn, T. Hunter, and R.L. Margolis. 2002. J. Cell Biol. 157:1175–1186). In this study, we identify an interaction between endogenous PRC1 and the previously uncharacterized kinesin KIF14 as well as other mitotic kinesins (MKlp1/CHO1, MKlp2, and KIF4) with known functions in cytokinesis (Hill, E., M. Clarke, and F.A. Barr. 2000. EMBO J. 19:5711–5719; Matuliene, J., and R. Kuriyama. 2002. Mol. Biol. Cell. 13:1832–1845; Kurasawa, Y., W.C. Earnshaw, Y. Mochizuki, N. Dohmae, and K. Todokoro. 2004. EMBO J. 23:3237–3248). We find that KIF14 targets to the central spindle via its interaction with PRC1 and has an essential function in cytokinesis. In KIF14-depleted cells, citron kinase but not other components of the central spindle and cleavage furrow fail to localize. Furthermore, the localization of KIF14 and citron kinase to the central spindle and midbody is codependent, and they form a complex depending on the activation state of citron kinase. Contrary to a previous study (Di Cunto, F., S. Imarisio, E. Hirsch, V. Broccoli, A. Bulfone, A. Migheli, C. Atzori, E. Turco, R. Triolo, G.P. Dotto, et al. 2000. Neuron. 28:115–127), we find a general requirement for citron kinase in human cell division. Together, these findings identify a novel pathway required for efficient cytokinesis.
