A P{SUPor-P} insertion within the first intron of the larger path transcription unit, path-RA.
pathKG06640, pathKG06640/pathdg50 or pathKG06640/Df(3L)BSC773 larvae show severe dendrite growth defects in the large C4da dendritic arbors.
pathKG06640 mutants are developmentally delayed, taking ~3 days longer than wild-type larvae to pupate. The wing discs of pathKG06640 third instar larvae are small when compared with similarly aged wild-type discs, but the extended mutant larval period allows discs to grow to roughly normal size by pupariation. The length of pupal development is not noticeably affected and resulting adults are markedly smaller than wild-type animals, are 40% lighter in weight, have wings with significant reductions in both cell number and size and eyes with small ommatidia. The salivary gland and the fat body are only modestly reduced. Additionally, pathKG06640 females fail to lay eggs.
pathKG06640/Df(3L)AC1 animals are even smaller than pathKG06640 homozygotes. These transheterozygotes are also developmentally delayed and female sterile.
Eyes in which many ommatidia are derived from pathKG06640 clones are indistinguishable in size from normal eyes.

The pathKG06640 reduced weight and small wing phenotypes are significantly rescued by expression of CG1139GS10666 under the control of Scer\GAL4arm.PS.
The growth and developmentally delayed phenotypes of pathKG06640 mutants are significantly rescued by the presence of combined heterozygous Tsc129 and gig192 mutations. About 10% of rescued females are able to lay a small number of eggs, some of which can develop into adult flies.
When clonal material in the eye is mutant for both gig192 and pathKG06640 in an otherwise heterozygous animal, the lethal effects of gig192 are suppressed, and about 10% of mutant animals, both males and females, eclose. Their eyes are smaller and bulge less than gig192 mutant eyes.
pathKG06640 is partially rescued by pathUAS.cGa/Scer\GAL4arm.PS
Expression of pathScer\UAS.cGa under the control of the constitutive Scer\GAL4arm.PS driver significantly rescues the growth, developmental delay and female sterility mutant phenotypes of pathKG06640 homozygotes. Rescued flies are slightly smaller than controls.
