Summary: Predicted to enable ATP hydrolysis activity; microtubule binding activity; and microtubule motor activity. Involved in several processes, including cytoskeleton-dependent cytokinesis; larval somatic muscle development; and microtubule bundle formation involved in mitotic spindle midzone assembly. Located in several cellular components, including male germline ring canal; somatic ring canal; and spindle. Part of centralspindlin complex. Is expressed in several structures, including embryonic central brain glial cell; ganglia; germline cell; head epidermis primordium; and sensory nervous system primordium. Human ortholog(s) of this gene implicated in congenital dyserythropoietic anemia type III. Orthologous to human KIF23 (kinesin family member 23). [provided by Alliance of Genome Resources, Dec 2024]

Centralspindlin proteins Pavarotti and Tumbleweed along with WASH regulate nuclear envelope budding.
Title: Centralspindlin proteins Pavarotti and Tumbleweed along with WASH regulate nuclear envelope budding.
elevated expression of Pav-KLP underlies transport and plasticity phenotypes in pathway mutants, indicating that Toll-6-FoxO signaling promotes MT dynamics by limiting Pav-KLP expression.
Title: A Toll receptor-FoxO pathway represses Pavarotti/MKLP1 to promote microtubule dynamics in motoneurons.
Data show that GTPase-activating protein (Tum/RacGAP) is required for the motor activity of kinesin-6 motor (Pav/kinesin-6).
Title: Tum/RacGAP functions as a switch activating the Pav/kinesin-6 motor.
Depletion of Pav-KLP in neurons strongly stimulated kinesin-1-driven sliding of long microtubules and neurite outgrowth, while its ectopic overexpression in the cytoplasm blocked both of these processes.
Title: Pavarotti/MKLP1 regulates microtubule sliding and neurite outgrowth in Drosophila neurons.
Study demonstrates the emerging role of centralspindlin (complex of two proteins Tum and Pav) in regulating cell migration and cell adhesion in addition to its previously known function during cytokinesis.
Title: Centralspindlin is required for thorax development during Drosophila metamorphosis.
Data show that Sticky (Sti), tile ring component Citron kinase (CIT-K) interacts directly with two kinesins, Nebbish and Pavarotti and that in turn these kinesins interact with each other and with another central spindle protein, Fascetto.
Title: Citron kinase controls a molecular network required for midbody formation in cytokinesis.
Results identify two modulators of the Wnt pathway, Tum and Pav, that have shared functions in cell division, which hints at a possible link between cytokinesis and Wnt activity during tumorigenesis.
Title: Cytokinesis proteins Tum and Pav have a nuclear role in Wnt regulation.
Pav-KLP transports elements of the actomyosin cytoskeleton
Title: Localization of Pavarotti-KLP in living Drosophila embryos suggests roles in reorganizing the cortical cytoskeleton during the mitotic cycle.
