Polo-like kinases
cycle with terminal differentiation. A unipotent host cell population acts as stem cells, which proliferate and migrate from the center of each lobule to the periphery, cease division, and die through apoptosis. During this journey they carry along their symbionts, which divide in the center, stop dividing, and subsequently become digested in the periphery. Digestion thus serves both in host no...
متن کاملCo-inhibition of polo-like kinase 1 and Aurora kinases promotes mitotic catastrophe
Mitosis is choreographed by a number of protein kinases including polo-like kinases and Aurora kinases. As these kinases are frequently dysregulated in cancers, small-molecule inhibitors have been developed for targeted anticancer therapies. Given that PLK1 and Aurora kinases possess both unique functions as well as co-regulate multiple mitotic events, whether pharmacological inhibition of thes...
متن کاملPolo-Like Kinase-1 Controls Aurora A Destruction by Activating APC/C-Cdh1
Polo-like kinase-1 (Plk1) is activated before mitosis by Aurora A and its cofactor Bora. In mitosis, Bora is degraded in a manner dependent on Plk1 kinase activity and the E3 ubiquitin ligase SCF-betaTrCP. Here, we show that Plk1 is also required for the timely destruction of its activator Aurora A in late anaphase. It has been shown that Aurora A destruction is controlled by the auxiliary subu...
متن کاملThe mitotic roles of Polo-like kinase.
The Polo-like protein kinases (Plks) are a conserved family of enzymes that play a variety of roles in the passage of cells through M phase (for reviews see Glover et al., 1998; Nigg, 1998). Named after the Drosophila polo gene originally identified through a recessive maternal effect lethal mutation, conserved Plk homologues have been identified in yeast, Xenopus, C. elegans and mammals. The i...
متن کاملPolo-like kinase 4 shapes up.
Polo-like kinase 4 (Plk4) is a master regulator of centriole duplication and targets to centrioles through the association of its cryptic polo box domain with centriole receptors. In this issue of Structure, Shimanovskaya and colleagues unveil a new dimeric architecture of Plk4's cryptic polo box that reveals a conserved mechanism for centriole targeting of the kinase.
