Gene Summary
Kinesin-like protein at 10A (Klp10A) encodes a member of the kinesin superfamily of motor proteins (KIF) and of the kinesin-13 family of microtubule depolymerases. It induces microtubule depolymerization to regulate the length and dynamics of microtubules in a variety of cell processes and structures such as the mitotic and meiotic spindles, the centriole and interphase microtubules.

Gene Group (FlyBase)
KINESINS -
Kinesin superfamily proteins (KIFs) are microtubule motor proteins which use the hydrolysis of ATP to drive directional movement along microtubules. KIFs possess a well-conserved 360 residue globular head domain which binds and hydrolyses ATP and interacts with microtubules. Many KIFs homodimerize via coiled-coil interactions in the stalk region. KIFs bind cargo through their variable tail regions and are involved in transporting organelles, protein complexes, mRNAs and the movement of spindles and chromosomes during cell division. (Adapted from FBrf0219884).
Protein Function (UniProtKB)
Required during anaphase to drive sister chromatid separation to promote flux by actively depolymerizing kinetochore microtubules at their pole-associated minus ends, thereby moving chromatids through a 'poleward flux' (PubMed:14681690, PubMed:20946984, PubMed:24100293). Involved in asymmetric cell division of sensory organ precursor (SOP) cells by playing a role in the asymmetric localization of Sara-expressing endosomes to the pIIa daughter cell but not to the pIIb cell. Klp98A targets Sara-expressing endosomes to the central spindle which is symmetrically arranged in early cell division. During late cytokinesis, central spindle asymmetry is generated by enrichment of Patronin on the pIIb side which protects microtubules from depolymerization by Klp10A while unprotected microtubules on the pIIa side are disassembled by Klp10A, leading to the asymmetric delivery of Sara-expressing endosomes to the pIIa daughter cell (PubMed:26659188).
(UniProt, Q960Z0)
Summary (Interactive Fly)

mitotic kinesin required to depolymerize microtubules at their pole-associated minus ends thereby moving chromatids by means of poleward flux - a stem cell centrosome-enriched kinesin that balances asymmetries in Drosophila male germline stem cell division

Model Confidence:
  • Very high (pLDDT > 90)
  • Confident (90 > pLDDT > 70)
  • Low (70 > pLDDT > 50)
  • Very low (pLDDT < 50)

AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.

        S2 cells treated with RNAi against Klp10A show reduced poleward flux rates of tubulin subunits in mitotic spindles and suppressed α-tubulin turnover at the microtubule minus ends of the spindles. The chromatid-to-pole velocity during anaphase is decreased in these cells. Pole-to-pole spindle lengths are significantly increased in the RNAi treated cells compared to controls.

        RNAi screen using dsRNA made from templates generated with primers directed against this gene results in aberrantly long spindles when assayed in S2 cells. This phenotype can be observed when the screen is performed with or without Cdc27 dsRNA.

        S2 cells transfected with dsRNA made from templates generated with primers directed against this gene show an expansion of the metaphase spindle.

        Klp10A is required to depolymerise microtubules at their pole associated minus ends, thereby moving chromatids by means of poleward flux.

        The introduction of Klp10A inhibitors into embryos rapidly alters the organisation of mitotic spindle microtubules. 30% form monopolar spindles, which assemble when centrosomes collapse back together after nuclear envelope breakdown. About 61% display abnormally long bipolar spindles. These bipolar spindles elongate continuously during prometaphase through anaphase and attain metaphase lengths approximately twice that of controls. The movement and segregation of chromosomes is also perturbed.

        dsRNA made from templates generated with primers directed against this gene tested in RNAi screen for effects on Kc167 and S2R+ cell morphology.
