      Reference

      Homozygous Tm1G5 mutant embryos show defects in nuclear distribution, with spindles and chromosomal alignment at metaphase appearing scrambled. In a small number of cases (less than 5% of mutant embryos) there appears to be supernumerary centrosomes with respect to nuclei. Tm1G5 mutant embryos display defective nuclear condensation.

      The P{PTT-GC}Tm1G5 insertion was originally curated under Tm2, but in reality it is inserted in Tm1.
