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)
Important role in mitotic dividing cells (PubMed:8227131). Microtubule motor required for spindle body separation (PubMed:8918872). Slow plus-end directed microtubule motor capable of cross-linking and sliding apart antiparallel microtubules, thereby pushing apart the associated spindle poles during spindle assembly and function (PubMed:19062285, PubMed:8589456, PubMed:8918872). Forms cross-links between microtubules within interpolar microtubule bundles (PubMed:19158379, PubMed:9885249). Contributes to the length of the metaphase spindle, maintains the prometaphase spindle by antagonizing Ncd, drives anaphase B, and also contributes to normal chromosome congression, kinetochore spacing, and anaphase A rates (PubMed:19158379). Displays microtubule-stimulated ATPase activity (PubMed:8589456). Required for normal fusome organization (PubMed:10469596). Required in non-mitotic cells for transport of secretory proteins from the Golgi complex to the cell surface (PubMed:23857769).
(UniProt, P46863)
Summary (Interactive Fly)

motor protein - crosslinking and sliding activities during mitosis facilitate accumulation within antiparallel interpolar MTs at the equator, where the motor generates force to drive spindle poleward flux and pole-pole separation

Subunit Structure (UniProtKB)

Homotetramer (PubMed:24714498, PubMed:8538794, PubMed:9885249). Consists of two pairs of polypeptides associated by coiled-coil interactions to form two homodimers (PubMed:8538794). The homodimers are linked by lateral interactions between their coiled-coil regions to form a bipolar homotetramer consisting of a central rod with two motor domains projecting from either end (PubMed:8538794). Parallel coiled coils extend from each pair of motor heads, switch to two antiparallel coiled coils in the central region and then back to parallel coiled coils (PubMed:24714498). Interacts with Wee1 (PubMed:19800237).

(UniProt, P46863)
Post Translational Modification

Phosphorylation is required for localization to mitotic spindles (PubMed:9885249). Phosphorylation of Thr-933 during mitosis controls association with the spindle apparatus (By similarity). Phosphorylated in vitro by Wee1 (PubMed:19800237).

Additional Descriptive Data

Klp61F transcripts were detected throughout the cytoplasm of unfertilized eggs. The maternal RNA persists until cellularization. During gastrulation, Klp61F transcripts are first detected in a wide band of ventral cells corresponding to the invaginating presumptive mesoderm. They are also seen in a more dorsal strip of cells and underneath the pole cells. Later embryos show expression in the head, along the cephalic furrow, along the ventral midline, and within the posterior region. After germ band retraction, expression is limited to the cells of the head and ventral neurogenic region. Regions of expression are well correlated with domains of cell division.

Klp61F transcripts are expressed throughout development. In adults, they are detected only in the gonads.

Additional Descriptive Data

Throughout mitosis, nonphosphorylated Klp61F protein is diffuse and cytoplasmic. Phosphorylated Klp61F shows a very different distribution. During interphase and prophase, the staining is punctate and concentrated in the nucleus. Occasional faint staining is seen in the centrosome in prophase. By metaphase, the staining localizes to the spindle and appears filamentous. Phospho-Klp61F is particularly concentrated on the half spindles and densely stained bridges between the spindles in the midzone. Lower level staining occurs at the oles and grainy cytoplasmic staining is observed. During anaphase A, the staining resembles metaphase. During anaphase B, nearly all the phospho-Klp61F is present in the spindle between the separating nuclei. Filaments of phospho-Klp61F protein staining cross the midzone while little or no staining is associated with the spindle poles and astral microtubules. During telophase, Klp61F staining is most pronounced on two adjacent patches on the remnants of the central spindle. EM studies suggest that the phospho-Klp61F motors form crosslinks between microtubules within interpolar microt bule bundles.

Klp61F protein localizes to the structural domains of the mitotic spindle throughout mitosis.

    Subunit Structure (UniProtKB)
    Homotetramer (PubMed:24714498, PubMed:8538794, PubMed:9885249). Consists of two pairs of polypeptides associated by coiled-coil interactions to form two homodimers (PubMed:8538794). The homodimers are linked by lateral interactions between their coiled-coil regions to form a bipolar homotetramer consisting of a central rod with two motor domains projecting from either end (PubMed:8538794). Parallel coiled coils extend from each pair of motor heads, switch to two antiparallel coiled coils in the central region and then back to parallel coiled coils (PubMed:24714498). Interacts with Wee1 (PubMed:19800237).

        RNAi screen using dsRNA made from templates generated with primers directed against this gene causes defects in spindle shape when assayed in S2 cells. This phenotype can be observed when the screen is performed with or without Cdc27 dsRNA.

        dsRNA directed against Klp61F inhibits protein secretion in S2 cells and causes aggregation and swelling of the Golgi membranes in more than 50% of the treated cells.

        dsRNA directed against this gene has been used in a screen for genes required for constitutive protein secretion.

        RNAi screen using dsRNA made from templates generated with primers directed against this gene causes a phenotype when assayed in DL2 cells: during mitosis, centrosome separation is prevented, resulting in monopolar spindles.

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

        RNAi screen using dsRNA made from templates generated with primers directed against this gene causes a phenotype when assayed in Kc167 and S2R+ cells: cell morphology is aberrant and there is an increased frequency of microtubule-based mitotic spindles, indicative of a failure in mitosis.

        Spindle pole movements in embryos are directed by a temporally coordinated balance of forces generated by three mitotic motors; cytoplasmic dynein, Klp61F and ncd. Dynein acts to move the poles apart throughout mitosis, and this activity is augmented by Klp61F after the fenestration of the nuclear envelope, which occurs at the onset of prometaphase. ncd generates forces that pull the poles together between interphase and metaphase, antagonising the activity of both cytoplasmic dynein and Klp61F and serving as a brake for spindle assembly.

        Klp61F cycles between spindles during mitosis and fusomes during interphase.

        Identification: Enhancer trap expression pattern survey for loci expressed in the ring gland.

        Klp61F is involved in the control of cell division.

        Klp61F protein, a homotetrameric BimC-related kinesin, consists of four kinesin-related polypeptides assembled into a bipolar aggregate with motor domains at opposite ends. Such a bipolar 'minifilament' could crosslink spindle microtubules and slide them relative to one another.

        Antibody staining reveals multiple bimC family members are expressed in Drosophila. Klp61F is an essential gene and biochemical and functional analysis of the protein demonstrates it is not functionally redundant for centrosome separation during neuroblast separation.

        Relationship to cloned Klp genes not known. Purified Klp61F behaves as a homotetrameric complex of four subunits that moves toward the plus ends of microtubule tracts at approximately 0.04μm/s.

        Encodes a 130kD kinesin related protein that behaves as a homotetramer and moves towards the plus ends of microtubules.

        Identified as a 130kD polypeptide in an ATP MAPs 1-24 hour embryonic fraction. A 490kD homotetrameric complex consisting of 4 130kD subunits display a 'slow' plus-end directed motor activity capable of moving single microtubules.

        The sequence of the Klp61F protein has been compared with the sequences of a variety of kinesin family proteins.

        Klp61F has been cloned, partially sequenced and its expression pattern analysed.

        Additional comments

        CG32318 appears to be a chimeric gene, with the 5' part of the gene derived from Klp61F and the 3' part of the gene derived from Psf1.

        "CG32318" is a putative chimeric gene derived from the "Klp61F" and "Psf1" genes (where coding sequences of the two parental genes contribute to the coding sequence of the chimeric gene).
