1bp deletion within the Mst77F coding sequence.
1bp deletion within the Mst77F coding sequence at amino acid 10.
Mst77FΔ1 homozygotes are male sterile; Mst77FΔ1/Mst77FΔ2 or Mst77FΔ2/Mst77FΔ3 transheterozygous males produce very rare progeny.
Mst77FΔ2 homozygotes and Mst77FΔ1/Mst77FΔ2 transheterozygotes present defective spermatid individualization, as compared to controls: spermatids are in disorganized bundles, retain the individualization complexes and present defects in nuclei morphology and chromatin compaction, as compared to controls.
Mst77FΔ1/Mst77FΔ2 is partially rescued by Mst77FmRFP1
Mst77FΔ1/Mst77FΔ2 is not rescued by Mst77FEGFP
Mst77FΔ2 fails to complement either Mst77FΔ1 or Mst77F[Δ3].
The male semi-sterility of Mst77FΔ1/Mst77FΔ2 heterozygotes is partially rescued by one copy of either Mst77F+tg or Mst77FT:Disc\RFP-mRFP, but not Mst77FT:Avic\GFP-EGFP.
