Comments

Imprecise excision of P{SUPor-P}phlKG04972; P-element sequences remain. Uncovers at least 14 kb of genomic sequence including the complete Ilp6 gene as well as at least 4 other genes (CG33218, CG2854, CG14050, CG34052).

(Grönke et al., 2010)

FlyBase Curator comment: Given the progenitor genotype, this excision event must also partially delete the phl gene.

(Grönke et al., 2010)

Imprecise excision of a progenitor insertion has resulted in a deletion.

Affected Genes Inferred by Location (0)
    If no genes are listed here, it may be because the affected region is very large. The JBrowse insert above may show an error for the same reason, and other FlyBase tools such as CytoSearch may also fail for large regions. You can contact FlyBase for more help.
    In these cases, there will be no "Export to Hitlist" button to the left.
    Phenotypic Data
    In combination with other aberrations

    Central nervous system neuroblasts of fed Df(1)Ilp6/Df(1)Ilp668 second instar larvae show a moderate reduction in EdU incorporation compared to controls.

    (Sousa-Nunes et al., 2011)
    NOT in combination with other aberrations

    Df(1)Ilp668 mutants are 100% viable; show a slight delay in egg-to-adult development time (males only); show a significant reduction in adult body weight; and males show normal paraquat resistance and starvation resistance.

    (Grönke et al., 2010)

    Mutant adults show a reduction in mass compared to controls.

    Mutant wandering stage larvae have normal levels of circulating carbohydrates and of triacylglycerides.

    The growth of Df(1)Ilp668 adults is compromised relative to that of control animals upon starvation (the mutant adults show a greater reduction of mass under starvation conditions compared to standard feeding conditions than do control adults).
