Phosphorylation of Eg5 at Thr937 (T937) by p34cdc2 (CDK1) is required for spindle localization: mutation of T937 to non-phosphorylatable alanine abolishes spindle localization, while T937S preserves it, establishing that cell-cycle-regulated phosphorylation at the conserved bimC C-terminal domain controls Eg5 targeting to the mitotic spindle. |

Monomeric human Eg5 is a slow, plus-end-directed ATPase: mantATP binding is rapid (2–3 µM⁻¹s⁻¹), ATP hydrolysis is fast (~15 s⁻¹), but ATP-dependent microtubule dissociation is rate-limiting (~8 s⁻¹), making the ATPase mechanism more similar to conventional kinesin than to minus-end motors Ncd/Kar3. |

Eg5 is downstream of and regulated by Bcr-Abl tyrosine kinase in Philadelphia chromosome-positive cells: imatinib treatment downregulates Eg5 expression in imatinib-sensitive but not imatinib-resistant (T315I) cells, placing Eg5 in the Bcr-Abl signaling axis. |

Inhibition of Eg5 upregulates Hsp70 transcriptionally via a cis-regulatory element in the Hsp70 promoter through the PI3K/Akt pathway; this Hsp70 induction is cytoprotective and reduces sensitivity to Eg5 inhibitors, while blocking Hsp70 or PI3K/Akt increases apoptosis. |

Parkin E3 ubiquitin ligase represses Eg5 gene transcription (without triggering proteasomal degradation of Eg5 protein) by blocking c-Jun binding to the AP-1 site in the Eg5 promoter; Parkin achieves this through multiple monoubiquitination of Hsp70, which inactivates JNK and reduces c-Jun phosphorylation. |

Tiam1-Rac signaling at centrosomes during prophase antagonizes Eg5-driven centrosome separation: Tiam1-depleted cells or Rac1-deficient cells escape monastrol-induced (Eg5-inhibited) mitotic arrest, and Eg5 suppression in Tiam1-depleted cells rescues increased centrosome separation and chromosome congression errors, placing Tiam1-Rac as the first identified force opposing Eg5 in prophase. |
