Expression of saxQ263D.Scer\UAS.T:Ivir\HA1 in Pdf-positive neurons, under the control of Scer\GAL4P2.4.Pdf does not affect circadian rhythm.

Overexpression of saxQ263D.Scer\UAS.T:Ivir\HA1 with Scer\GAL4A9 leads to extra vein material between the region of L3 and L5 with slight wing blistering, also affecting the posterior crossvein pattern.

Pan-neuronal expression of saxQ263D.Scer\UAS.T:Ivir\HA1 does not generate appreciable motor axon phenotypes.

Expression of saxQ263D.Scer\UAS.T:Ivir\HA1 in the wing under the control of Scer\GAL4A9 results in mild wing-vein patterning defects.

Scer\GAL4GMR.PF-driven overexpression of saxQ263D.Scer\UAS.T:Ivir\HA1 has no effect on eye development.

Expression of saxQ263D.Scer\UAS.T:Ivir\HA1 in the wing with Scer\GAL4ptc-559.1 induces patterning abnormalities including extensive ectopic vein, fusion of longitudinal veins, and loss of intervein regions.

Expression of tkvQ199D.UAS.Tag:HA, under the control of either Scer\GAL4ChAT.7.4, or Scer\GAL4eve.RN2 has no effect on the synaptic current amplitude in aCC/RP2 neurons compared to controls.

Flies expressing saxQ263D.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4A9 have ectopic and thickened wing veins with a small amount of wing blistering in the region of the posterior crossvein.

Over-activation of the BMP pathway, by co-expressing tkvQ199D.Scer\UAS.T:Ivir\HA1 and saxQ263D.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4nos.UTR.T:Hsim\VP16, leads to an increase of early somatic cells in the male gonad, but no increase in somatic cell proliferation.

Co-expression of tkvQ253D.Scer\UAS.cNb and saxQ263D.Scer\UAS.T:Ivir\HA1 in Pdf-positive neurons, under the control of Scer\GAL4P2.4.Pdf results in a long period phenotype.

Introducing one copy of fussScer\UAS.C almost completely rescues the saxQ263D.Scer\UAS.T:Ivir\HA1, Scer\GAL4A9 wing phenotype - vein formation is close to wild type.

Pan-neuronal expression of saxQ263D.Scer\UAS.T:Ivir\HA1 reduces the incidence of defasciculation from 64% to 30% in fracΔ1 mutants.

Co-expression of saxQ263D.Scer\UAS.T:Ivir\HA1 partially suppresses the motor axon mis-projections and hypo-fasciculation found upon expression of fracScer\UAS.cMa (from 55% to 27%, when both transgenes are expressed under the control of either or both Scer\GAL4elav-C155 and Scer\GAL4how-24B).

Expression of MadSDVD.Scer\UAS in animals expressing saxQ263D.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4A9 does not enhance the wing vein patterning defects.

Expression of saxQ263D.Scer\UAS.T:Ivir\HA1 in animals expressing tkv1AΔGS.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4A9 enhances the wing phenotype.

Expression of saxQ263D.Scer\UAS.T:Ivir\HA1 in animals expressing tkv1-A-T318D.Scer\UAS under the control of Scer\GAL4A9 enhances the wing phenotype.

Expression of saxQ263D.Scer\UAS.T:Ivir\HA1 in animals expressing tkv1-A-T485D.Scer\UAS under the control of Scer\GAL4A9 slightly enhances the wing phenotype.

Expression of saxQ263D.Scer\UAS.T:Ivir\HA1 in animals expressing tkv1-A-T318D-T485D.Scer\UAS under the control of Scer\GAL4A9 results in a wing phenotype similar to co-expression with the single mutant tkv1-A-T485D.Scer\UAS.

Expression of saxQ263D.Scer\UAS.T:Ivir\HA1 in motor neurons (under the control of Scer\GAL4OK6) rescues bouton number and EJP phenotypes in Ranbp1170 mutants, although mEJP frequency is not rescued.

Expression of saxQ263D.Scer\UAS.T:Ivir\HA1 in muscle (under the control of Scer\GAL4G14) does not rescue bouton number or mEJP and EJP phenotypes in Ranbp1170 mutants.

Overexpression of saxQ263D.Scer\UAS.T:Ivir\HA1 enhances the adult visual system degeneration seen in Scer\GAL4GMR.PF, Ppt1Scer\UAS.cKa flies.

The wing patterning phenotypes resulting from the expression of saxQ263D.Scer\UAS.T:Ivir\HA1 with Scer\GAL4ptc-559.1 are enhanced by the co-expression of kek5Scer\UAS.T:Avic\GFP, and there is an additional decrease in wing size.

Flies expressing saxQ263D.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4A9 and also carrying tkvDE-Q199D.tld.T:Ivir\HA1 have blistered, darkly pigmented wings. Wings discs of these animals show overgrowth.
