Deletion of part of Wdr62. Generated by FLP-mediated recombination between the PBac{PB}Wdr62c04508 and PBac{PB}Wdr62c04728 progenitor insertions.
Inferred boundaries of a deletion generated by FLP-mediated recombination between the PBac{PB}Wdr62c04508 and PBac{PB}Wdr62c04728 progenitor insertions, which removes the upstream-most coding exon from most Wdr62 isoforms.
Wdr62Δ2a/Df(2L)Exel8005 is somewhat lethal at the pupal stage, with around 50% adult escapers.
Loss of microtubule-organizing center (MTOC) activity on the apical centrosome during interphase leads to two centrioles devoid of microtubules in Wdr62Δ2a/Df(2L)Exel8005 third instar larval neuroblasts.
Wdr62Δ2a/Df(2L)Exel8005 third instar larval neuroblasts display a centrosome asymmetry phenotype, with weaker microtubule intensity on maturing centrosome and metaphase spindles compared to wild type.
In Wdr62Δ2a/Df(2L)Exel8005 third instar larval neuroblasts the apical centrosome is no longer stationary and shows a more widespread distribution (often maturing close to basal cortex), and both track length and overall centrosome displacement is similar in apical and basal centrioles; track length is significantly increased in the apical and basal centriole and centrosome displacement is significantly larger in the apical centriole compared to wild type.
Wdr62Δ2a/Df(2L)Exel8005 third instar larval neuroblasts contain misaligned spindles with low frequencies, along with incorrectly positioned centrosomes leading to mild centrosome segregation defects.
Expression of Wdr62Scer\UAS.T:Zzzz\dendGFP-Dendra2 driven by Scer\GAL4wor.PU rescues the centrosome asymmetry phenotype (weaker microtubule intensity on maturing centrosome and metaphase spindles) seen in Wdr62Δ2a/Df(2L)Exel8005 third instar larval neuroblasts.
