322bp deletion that removes the first FIG4 exon (including the translation start site) and part of the second exon (coordinates 2L:4465214..4465535 , release 6 genome sequence, are deleted). The deletion introduces a frameshift in the remaining open reading frame. Generated by imprecise excision of P{EP}G3648.
A 322 bp deletion associated with the imprecise excsion of P{EP}G3648.
FIG4Δ1 flies are homozygous viable but show age-progressive flight defects.
FIG4Δ1 homozygous as well as FIG4Δ1/Df(2L)FIG4-Δ2 transheterozygous third instar larvae show expansion of lysosomal structures in the somatic muscles and motor neurons in the larval CNS but no defects in autophagosome formation are observed in fat bodies of starved FIG4 homozygous larvae.
FIG4Δ1 is rescued by FIG4UAS.Tag:MYC/Scer\GAL4Mef2.PU

Expression of FIG4Scer\UAS.T:Hsap\MYC under the control of Scer\GAL4Mef2.PU fully rescues the lysosome expansion phenotype in somatic muscles of FIG4Δ1 homozygous third instar larvae.
