UAS regulatory sequences drive expression of the Nep4 A isoform which carries the amino acid replacement E873Q in the conserved HExxH motif, which is predicted to result in a catalytically inactive protein.
larval somatic muscle cell | third instar larval stage, with Scer\GAL4Mef2.5xCD
Third instar larvae expressing Nep4HQxxH.Scer\UAS.A under the control of Scer\GAL4Mef2.5xCD show muscle degeneration.
