Description

In addition to the previously reported deletion in the catalytic core of mle, the mle9 mutant also contains a 21bp deletion that results in the loss of 7 amino acids from the C-terminal RGG-box domain (the first of two GGGYGNN repeats immediately downstream of the nuclear localization signal is lost).

49bp deletion that removes 8bp of the last intron and 41bp of the beginning of the last exon of mle. The deletion removes the 3' splice site of the last intron, and mRNA analysis indicates that splicing uses the first alternative AG site, shifting the beginning of the last exon, and resulting in a deletion of 72bp from the last exon in mle mRNAs expressed in the mutant. This results in the deletion of 24 amino acids (536-559 of the RA isoform) from the expressed protein, removing sequence encoding the conserved motif III of the first RecA-like domain.

Detailed Description
Statement
Reference

Homozygous males show appreciable survival to larval stages (day 5) in the presence of infection with the "male-killing" bacterium S.poulsonii when their mother is also homozygous, while infected heterozygous sibling males show no survival to day 5. Homozygous and heterozygous infected male embryos derived from heterozygous females show no survival to day 5.

Statement
Reference

The rough eye phenotype of flies expressing BEAF-32BID.Scer\UAS.T:Ivir\HA1,T:SV40\nls2 under the control of Scer\GAL4ey.PH is not enhanced by mle9/+.

Ovaries of homozygous ovoD1rv22 females contain germline chambers in less than 20% of cases. This phenotype is partially suppressed if the females are also carrying mle9/mle9. ovoD1rv23/ovoD1rv22; mle9/mle14 ovaries are phenotypically mosaic, containing germ cells of both male and female morphology. The mosaicism can be at the level of whole ovaries or ovarioles.

Female lethality of EMS induced vir mutations cannot be rescued by the mle9 mutation.

Mutant phenotype can be rescued by P element mediated transformation of a wild type mle gene copy.

Comments

msl-1 is not associated with the X chromosome of male larvae. Salivary gland chromosomes of flies, with introduction of mle9 into virts homozygous female larvae, show no evidence of H4Ac16 binding.
