Insertion 69bp upstream of the start codon, within the predicted 5' untranslated region.
Homozygous embryos first show abnormalities during stage 12. At this and later stages, defects are mostly restricted to the developing central nervous system which contains a lower number and more irregular distribution of nuclei compared to in controls. In addition, pyknotic and enlarged, over-replicated nuclei are also seen in the mutant central nervous system.
cal1c03646 is rescued by cal1EGFP
Expression of one of cal1N.Scer\UAS.T:Avic\GFP-EGFP, cal1M.Scer\UAS.T:Avic\GFP-EGFP or cal1C.Scer\UAS.T:Avic\GFP-EGFP under the control of Scer\GAL4sca-537.4 fails to rescue normal cell proliferation in cal1unspecified embryos.
Co-expression of both cal1N.Scer\UAS.T:Avic\GFP-EGFP and cal1C.Scer\UAS.T:Avic\GFP-EGFP under the control of Scer\GAL4sca-537.4 fails to rescue normal cell proliferation in cal1unspecified embryos.
Expression of either cal1Scer\UAS.T:Avic\GFP-EGFP or cal1N-C.Scer\UAS.T:Avic\GFP-EGFP under the control of Scer\GAL4sca-537.4 rescues normal cell proliferation in cal1unspecified embryos.
