Gene Snapshot
costa (cos) encodes a kinesin-like protein and a key component in the Hedgehog (Hh) pathway that is involved in pattern formation and growth control. It forms a complex with the product of fu to restrict the activity of the Hh pathway transcription factor encoded by ci. [Date last reviewed: 2019-03-07]
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).
HEDGEHOG SIGNALING COMPLEX -
The Hedgehog signaling complex (HSC) is involved in hedgehog signaling pathway. In the absence of hh, HSC promotes the proteolytic processing of the transcription factor and HSC component ci to its repressor form. hh activation of the pathway blocks the processing of ci, allowing the accumulation of the full-length activator protein. (Adapted from FBrf0174381.)
Pathway (FlyBase)
Negative Regulators of Hedgehog Signaling Pathway -
Negative regulators of hedgehog signaling down-regulate the pathway, resulting in the repression of transcription of hh-responsive genes.
Hedgehog Signaling Pathway Core Components -
The hedgehog signaling pathway is initiated by hedgehog (hh) ligand binding to the extracellular domain of patched receptor (ptc), leading to the derepression of smoothened (smo) activity. Activation of the atypical GPCR smo results in the accumulation of the transcriptional activator form of cubitus interruptus (ci) and the derepression/activation of hh target genes. In the absence of hh, smo is repressed by ptc and ci is processed to a truncated repressor form. (Adapted from FBrf0220683 and FBrf0231236).
Protein Function (UniProtKB)
Regulates cubitus interruptus (ci) processing by recruiting multiple kinases to promote its efficient phosphorylation. Scaffolds multiple kinases and ci into proximity to promote its hyperphosphorylation, which then targets it for SCFSlimb/proteasome-mediated processing to generate its repressor form. Hh signaling inhibits ci phosphorylation by interfering with the cos-ci-kinases complex formation. Negatively regulates hh-signaling pathways during various processes, including photoreceptor differentiation (PubMed:25639794, PubMed:27195754). May negatively regulate a hh-signaling pathway which functions in the intestinal immune response to bacterial uracil by activating the Duox-dependent production of reactive oxygen species (ROS) (PubMed:25639794).

Phenotypic Description (Red Book; Lindsley and Zimm 1992)
cos: costa (P. Simpson)
Homozygotes, hemizygotes, and heteroallelic heterozygotes for class I alleles die as embryos with a normal cuticular phenotype. When derived from homozygous ovarian clones, however, abnormal deletion-duplication patterns in each segment are observed; posterior rows of abdominal denticles are replaced by mirror-image duplications of the anterior rows, including the segmental boundary, which is thereby duplicated; thoracic denticle belts missing; cos1 especially severely affected in this regard, including loss of entire segments. Heterozygotes derived from homozygous ovarian clones show slightly abnormal segmental patterning. Flies heterozygous for class I alleles or cos deficiencies and at the same time heterozygous for Cos alleles display pattern duplications of wings and halteres. Class II alleles are hemizygous lethal but homozygous viable. They display wing and haltere duplications indistinguishable from those found for cos1/Cos1 heterozygotes as described by Whittle. Flies heterozygous for class III alleles and Cos show moderately reduced viability and occasional wing duplications; flies homozygous for class III alleles show reduced viability and have wild-type phenotype, but enhance the pattern duplications associated with Cos/+; hemizygotes for class III alleles or heterozygotes with class I alleles are lethal or nearly so in the presence of Cos, the survivors invariably exhibiting pattern duplications of wings and halteres.

Additional Descriptive Data

In syncytial embryos, cos protein is distributed uniformly in the cortical cytoplasm. In the late syncytial embryo, it accumulates between and apical to nuclei. From the surface, the pattern looks like a honeycomb. Throughout cellularization, cos protein is associated with furrow canals and during late cellularization is associated with expanded furrow canals. In cellular blastoderm embryos and during gastrulation, cos protein is in the cytoplasm and at the periphery of all cells. A striped pattern of cos protein is observed beginning in late stage 9 and decaying in stage 12. Each stripe is continuous along the dorsal/ventral axis both in the ectoderm and the underlying mesoderm. The stripes appear to form in the anterior compartment of each segment. In wing discs, cos protein levels are elevated in the anterior compartment

        cos blocks smo phosphorylation through binding with smo.

        Identified as a component of the hh signalling pathway in a genome-wide RNAi screen. dsRNA made from templates generated with primers directed affects the extent of expression of a hh signaling reporter construct in Clone 8 cells.

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

        dsRNA made from templates generated with primers against this gene tested in an RNAi assay in S2 cells.

        Epistatic analysis places cos function downstream of ptc and smo.

        The last 301 amino acids of the cos COOH terminus are sufficient to provide full association with smo.

        1 allele of cos been recovered in a screen for mutations with mutant phenotypes in clones in the wing.

        fu protein phosphorylates cos protein. The primary site of phosphorylation is Ser-572, with Ser-931 being phosphorylated to a lesser extent.

        Mutants are isolated in a screen of the second chromosome isolating disc morphology defects.

        hh elicits signal transduction via a complex that includes the products of the fu, ci and cos genes. The complex binds with high affinity to microtubules in the absence of hh protein, but not when hh is present. The complex may facilitate signalling from hh by governing access of the ci product to the nucleus.

        cos encodes a kinesin-related protein that accumulates preferentially in cells capable of responding to hh signal. The product is cytoplasmic and binds microtubules. The ci protein associates with the cos product in a large protein complex, suggesting that cos directly controls the activity of ci.

        The small lobe of fu may play a role in generating the neomorphic cos phenotype displayed by an unregulated fu protein in a Su(fu)- background.

        cos function is required maternally for the patterning of the central portion of each segment, in the absence of cos activity the central portion is replaced by a mirror image duplication of the anterior partion. The cos protein may be involved in localisation or transport of other segment polarity gene products within the cell, facilitating cell polarisation.

        Viable mutations in the segmentation genes cos cause specific alterations in dpp expression within the anterior-posterior compartment boundary of the wing disc.

        Mutants display hyperplastic phenotype, imaginal disc overgrowth.

        cos negatively regulates ptc and wg transcription.

        Genetic and developmental characteristics of the imaginal disc overgrowth mutant have been determined.

        wg and en expression patterns are studied in all known segment polarity mutants to investigate the requirement of other segment polarity genes in mediating the maintenance of wg and en.

        cos suppresses the segment polarity and zygotic phenotype of one class of fu alleles and causes a lethal interaction with the other class of fu alleles.

        cos falls into the segment polarity class of genes, and has both a maternal and a zygotic action.

        Leaky alleles of cos display wing duplications that are part of a larger syndrome of polarity defects that affect the embryonic and imaginal segment. The dominant phenotype seen in flies heterozygous for the neomorphic "Cos" mutants is the result of a reduced level of function at the cos locus. Haploidy for cos enhances, whereas triploidy for cos suppresses the phenotype of "Cos" heterozygotes.

        Homozygotes, hemizygotes and heteroallelic heterozygotes for class I alleles die as embryos with a normal cuticular phenotype. When derived from homozygous ovarian clones, however, abnormal deletion-duplication patterns in each segment are observed; posterior rows of abdominal denticles are replaced by mirror-image duplications of the anterior rows, including the segmental boundary, which is thereby duplicated; thoracic denticle belts missing; cos1 especially severely affected in this regard, including loss of entire segments. Heterozygotes derived from homozygous ovarian clones show slightly abnormal segmental patterning. Flies heterozygous for class I alleles or cos deficiencies and at the same time heterozygous for Cos alleles display pattern duplications of wings and halteres. Class II alleles are hemizygous lethal but homozygous viable. They display wing and haltere duplications indistinguishable from those found for cos1/Pka-C1Cos-1 heterozygotes as described by Whittle. Flies heterozygous for class III alleles and Cos show moderately reduced viability and occasional wing duplications; flies homozygous for class III alleles show reduced viability and have wild-type phenotype, but enhance the pattern duplications associated with Cos/+; hemizygotes for class III alleles or heterozygotes with class I alleles are lethal or nearly so in the presence of Cos, the survivors invariably exhibiting pattern duplications of wings and halteres.
