Detailed Description

Reference

Adulthood-induced TER94k15502 homozygous clones in mosaic midguts are larger (i.e. with more cells) than control clones.

TER94k15502 mutants show locomotive defects in the third instar larval stage (crawling speed and distance) and in 3 days old adults, but not 10 and 30 days old adults (climbing score).

Heterozygosity for TER94k15502 ameliorates the rough eye and photoreceptor cell phenotypes resulting from the overexpression of TER94R152H.Scer\UAS under the control of Scer\GAL4GMR.PF.

Heterozygosity for TER94k15502 ameliorates the rough eye and photoreceptor cell phenotypes resulting from the overexpression of TER94R188Q.Scer\UAS under the control of Scer\GAL4GMR.PF.

Heterozygosity for TER94k15502 ameliorates the rough eye and photoreceptor cell phenotypes resulting from the overexpression of TER94A229E.Scer\UAS under the control of Scer\GAL4GMR.PF.

At the third instar stage, the morphology of TER94k15502 mutant neuronal clones is also wild-type, although these cells die shortly after the onset of the pupal stage.

TER94k15502/+ mutant adults do not exhibit significant defects in phototaxis at 20 days of light exposure (dle), nor any defects in geotaxis at 20 or 30 dle, as compared to controls.

Female germ-line clones formed germaria that give rise to stage six or seven egg chambers before degeneration occurs.

Females carrying homozygous germline clones do not lay eggs. Homozygous clones on the head, scutellum or sternopleurum result in bristle loss.

Heterozygous TER94k15502 enhances the rough-eye phenotype induced by Scer\GAL4GMR.PS>cazVDRC.cUa.

Flies carrying TER94k15502 and Scer\GAL4elav.PLu>cazVDRC.cUa have significantly worse locomotive ability than do flies with Scer\GAL4elav.PLu>cazVDRC.cUa alone.

The decreased branch length phenotype caused by Scer\GAL4elav.PLu>cazVDRC.cUa in motor neurons is significantly enhanced by TER94k15502/+.

The decrease in the number of synaptic boutons in Scer\GAL4elav.PLu>cazVDRC.cUa-expressing larvae is significantly enhanced by TER94k15502/+. However, there is significant differences in the size of synaptic boutons among these genotypes.

Expression of Der-1Scer\UAS.cLa under the control of Scer\GAL4GMR.PF in a heterozygous TER94k15502 mutant background results in lethality.

The small eye phenotype characteristic for adult flies expressing atlScer\UAS.T:Hsap\MYC under the control of Scer\GAL4GMR.PF is significantly ameliorated by combination with a single copy of TER94k15502.

TER94k15502/+ strongly suppresses the retinal degeneration and photoreceptor neuron loss seen in flies expressing ninaEP37H at both 20 and 30 days of light exposure; and rescues the visual processing defects seen in these flies at 20 days of light exposure.

Excision of the P{lacW} element fully reverts the lethal phenotype.

Phenotypic analysis suggests an allelic series, starting from the strongest: TER94k15502, TER9426-8, TER9403775, TER9422-30, TER9414-23, TER9422-26, TER947-12 and TER9443-8.
