Summary: Enables minus-end-directed microtubule motor activity and plus-end-directed microtubule motor activity. Involved in microtubule depolymerization; regulation of mitotic sister chromatid segregation; and sister chromatid segregation. Located in astral microtubule; kinetochore; and kinetochore microtubule. Used to study breast cancer; colorectal cancer; lung cancer; prostate cancer; and uterine cancer. Human ortholog(s) of this gene implicated in microcephaly with or without chorioretinopathy, lymphedema, or mental retardation. Orthologous to human KIF11 (kinesin family member 11).

These results suggest that Cin8-PP1 plays a critical role at kinetochores to promote accurate chromosome segregation by controlling Ndc80 attachment to microtubules.

Bidirectional Kinesin Cin8 Produce Additive Forces in Both Directions of Movement
Title: Ensembles of Bidirectional Kinesin Cin8 Produce Additive Forces in Both Directions of Movement.
Data suggest that approximately four Cin8 motor domains can bind each alpha/beta-tubulin dimer within microtubule lattice; Cin8 binds microtubules not only at the canonical site, but also one or more separate "non-canonical" sites.
Title: The yeast kinesin-5 Cin8 interacts with the microtubule in a noncanonical manner.
The tail domain is one of the factors that regulate Cin8 directionality.
Title: Deletion of the Tail Domain of the Kinesin-5 Cin8 Affects Its Directionality.
Cin8 mutants lacking critical CDK phosphorylation sites suppress the requirement for Cdc14 and Cdc5 in anaphase spindle elongation.
Title: FEAR-mediated activation of Cdc14 is the limiting step for spindle elongation and anaphase progression.
The deletion mutant cells exhibited reduced midzone-directed motility and efficiency to support spindle elongation, indicating the importance of directionality control for the anaphase function of Cin8.
Title: Directionality of individual kinesin-5 Cin8 motors is modulated by loop 8, ionic strength and microtubule geometry.
Dephosphorylation of Cin8 promotes its binding to the spindle microtubules before the onset of anaphase.
Title: Phospho-regulation of kinesin-5 during anaphase spindle elongation.
