TL;DR: This study identifies HURP as a novel component of the Ran-importin beta-regulated spindle assembly pathway, supporting the conclusion that K-fiber formation and stabilization involves both the centrosome-dependent microtubule search and capture mechanism and the RanGTP pathway.

TL;DR: This work uses a yeast two-hybrid screen to show that a new human cyclin (cyclin H) is a MO15-associated protein and enhances the kinase activity of MO15 towards Cdk2/cyclin A, demonstrating that a cyclin/kinase complex can function as a regulator of other cyclin-dependent kinases complexes, and suggesting that cyclin /kinase cascades may exist.

TL;DR: It is shown that the microtubule-associated protein regulating cytokinesis (PRC1) is an anaphase-specific binding partner for Plk1, and that this interaction is required for cytokinesIS.

TL;DR: A molecular characterization of a human p40MO15 homologue and its associated CAK activity suggests that the phosphorylation state of threonine 161 in p34cdc2 (and the corresponding residue in other cdks) may be regulated primarily by the availability of the cdk/cyclin substrates, and by phosphatase(s).

TL;DR: It is proposed that Nlp plays an important role in microtubules organization during interphase, and that the activation of Plk1 at the onset of mitosis triggers the displacement of Nlp from the centrosome, allowing the establishment of a mitotic scaffold with enhanced microtubule nucleation activity.
