Insertion of a G nucleotide 1596bp downstream of the ATG start codon. This results in a frameshift that causes a stop codon 10 amino acids downstream of the insertion. Therefore this allele produces a 522 amino acid residue protein, which removes 254 amino acids from the C-terminal end compared to the wild-type protein. (Revision of data reported in FBrf0230407).
Transcript levels are reduced compared to wild type; no band representing either a wild type or truncated translated product is detected on a Western blot.
G
The insertion of a G nucleotide between these two bases results in a frameshift and early translation termination 10 amino acids downstream.
semi-sterile | female (with Df(2L)Exel6047)
viable (with Df(2L)Exel6047)
ovary (with Df(2L)Exel6047)
Mcm10FS/Df(2L)Exel6047 are viable and do not show increased adult mortality rates compared to heterozygote controls. Mcm10FS/Df(2L)Exel6047 have reduced female fecundity.
Percentage of Mcm10FS/Df(2L)Exel6047 embryos hatching is increased with wild type maternal (and slightly by paternal) allele donation.
Mcm10FS/Df(2L)Exel6047 are seen in early embryonic cell cycle stages significantly more than wild type, most mutant pre-gastrulating embryos have chromosome fragmentation, females show significant reductions in egg deposition compared to wild type and frequently (with incomplete penetrance and sometimes asymmetric) display small ovaries largely devoid of vitellogenic follicles. In contrast to wild type ovarioles, Mcm10FS/Df(2L)Exel6047 display long thin strings of somatic cells.
Df(2L)Exel6047/Mcm10FS is partially rescued by Scer\GAL4VP16.nanos.UTR/Mcm10UAS.cRa
Mcm10Scer\UAS.cRa driven by Scer\GAL4nos.UTR.T:Hsim\VP16 partially rescues reduced fecundity, percentage of embryos hatching and early embryonic cell cycle deficiencies in Mcm10FS/Df(2L)Exel6047 female flies.
