Summary: Enables cytoskeletal motor activity. Involved in several processes, including generative cell mitosis; microtubule cytoskeleton organization; and nuclear chromosome segregation. Located in several cellular components, including kinetochore; nucleus; and spindle. Part of microtubule associated complex. Is expressed in several structures, including CNS glial cell; central brain primordium; cuboidal/columnar epithelium; ganglia; and gonad. Orthologous to several human genes including KIF18A (kinesin family member 18A). [provided by Alliance of Genome Resources, Dec 2024]

these results suggest that the MT-stabilizing activity of kinesin-8 is critical for stable kinetochore-MT attachment.
Title: Drosophila kinesin-8 stabilizes the kinetochore-microtubule interaction.
Results suggest that KLP67A plays an important role in controlling the dynamics of microtubule (MT) plus ends to limit MT polymerization thereby preventing the plus ends from extending far enough to reach the opposite pole.
Title: Coupling between microtubule sliding, plus-end growth and spindle length revealed by kinesin-8 depletion.
The data reveal that, unlike other metazoan kinesin-8 proteins, Klp67A binds the nascent prophase and mature metaphase kinetochore. From this location, Klp67A uses its motor activity to ensure chromosome alignment and proper spindle length.
Title: Drosophila Klp67A binds prophase kinetochores to subsequently regulate congression and spindle length.
KLP67A is essential for spindle assembly during mitosis and male meiosis
Title: The Drosophila kinesin-like protein KLP67A is essential for mitotic and male meiotic spindle assembly.
Klp67A is a member of the Kip3 subfamily of microtubule destabilising kinesins, the loss of which results in abnormally long and stable pre-anaphase microtubules
Title: Klp67A destabilises pre-anaphase microtubules but subsequently is required to stabilise the central spindle.
Hypomorphic mutations of klp67A may lead to segregation defects
Title: Drosophila Klp67A is required for proper chromosome congression and segregation during meiosis I.
