Additional Comments

Genetic Interactions

Statement

Reference

Shorter egg length in sqh^E20.E21/+ is enhanced in Pkn^1T/Pkn^1T or Pkn^2T/Pkn^2T germline clones.

(Ferreira et al., 2014)

Introducing one copy of sqh^E20.E21 into aur^ST, aur^IM, or aur^WK mutants significantly enhances aur mutant lethality.

A rok²/+ heterozygous background suppresses the enhanced lethality of aur^IM females bearing one copy of sqh^E20.E21, and ameliorates the enhanced rough eye phenotype of these flies.

A rok²/+ heterozygous background suppresses the enhanced lethality of aur^WK females bearing one copy of sqh^E20.E21, and ameliorates the enhanced rough eye phenotype of these flies.

(Moon and Matsuzaki, 2013)

sqh^E20.E21 enhances the neuroepithelial defects of asp^E3 larval brains.

(Rujano et al., 2013)

Expression of sqh^E20.E21 suppresses the short wing and deformed T3 leg phenotypes of Drak^KO mutants.

(Neubueser and Hipfner, 2010)

The wing defects seen in flw¹/Y ; puc^A251.1F3/+ flies are suppressed to wild type by sqh^E20.E21.

(Kirchner et al., 2007)

The epithelial polarity defects and genomic polyploidy defects seen in lkb1^X5 larvae are suppressed by sqh^E20.E21.

The cuticle defects seen in mutant embryos derived from SNF1A^D1 homozygous female germline clones are partially suppressed by sqh^E20.E21; the fraction of embryos that form cuticle is increased from approximately 10% to approximately 30%.

The fraction of SNF1A^D1 mitotic larval brain neuroblasts that show extreme polyploidy is decreased if the larvae are also mutant for sqh^E20.E21.

(Lee et al., 2007)

Expression of one copy of the sqh^E20.E21 transgene partially restores axial expansion in Cp190² germ-line clone embryos.

(Chodagam et al., 2005)

A single copy of the sqh^E20.E21 transgene is able to considerably suppress the sti^{dsRNA.Sym.Scer\UAS} (under the regulation of Scer\GAL4^ey.PB) rough eye phenotype.

(D'Avino et al., 2004)

The amount of Mbs^T541 photoreceptor clones that are mislocalized to the basal region of the eye disc is increased when these discs carry one copy of sqh^E20.E21 (a transgene that contains two phosphomimetic mutations).

(Lee and Treisman, 2004)

The flw¹ mutation is lethal in combination with the phosphomimetic sqh^E20.E21 mutation. The amount of blistering and crumpling of wings in flies expressing MYPT-75D^{F117A.Scer\UAS} under the control of Scer\GAL4^Bx-MS1096 is enhanced by sqh^E20.E21.

(Vereshchagina et al., 2004)

The small, rough eye phenotype of Rac1^GMR.PN flies is enhanced by heterozygosity for sqh^E20.E21.

(Tan et al., 2003)

4% of rok²/Y ; sqh^E20.E21/+ flies survive to adulthood. The multiple wing hair phenotype caused by rok² is almost completely suppressed by sqh^E20.E21. The dsh¹ multiple hair phenotype but not the hair misorientation phenotype is suppressed by sqh^E20.E21.

Expressing one copy of the sqh^E20.E21 transgene restores axial expansion in sqh¹ germline clones and substantially restores both oogenesis and subsequent axial expansion in sqh^AX3 germline clones.
