pim promoter sequences drive expression of a mutated pim ORF and 3'UTR; the destruction box has been mutated from KKPLGNLDN to AKPAGNLDA and the KEN motif found near the N-terminal end of the coding sequence has been mutated to AAA. The coding sequence is tagged with Tag:MYC. Generated by excision of the FRT stop cassette from pimkenadba.g.FRT.Tag:MYC.
Cell division is normal during early embryogenesis in pimkenadba.g.T:Hsap\MYC embryos, but by stage 14, the CNS contains many large polyploid cells - indicating inhibition of mitosis.
pimkenadba.g.Tag:MYC is an enhancer of increased occurrence of cell division | embryonic stage phenotype of CycAδ1-53.UAS, Scer\GAL4prd.RG1
pimkenadba.g.Tag:MYC fails to rescue pimIL
Inhibition of sister chromatid separation during mitosis 15 in pimIL/pimIL embryos (from pimIL/+ mothers) is not rescued by pimkenadba.g.T:Hsap\MYC.
