UAS regulatory sequences drive expression of the Nep4 A isoform in which the second of the two His residues of the conserved HExxH motif has been mutated to Phe, which is predicted to result in a catalytically inactive protein.
larval somatic muscle cell | larval stage, with Scer\GAL4Mef2.5xCD
Larvae expressing Nep4HExxF.Scer\UAS.A under the control of Scer\GAL4Mef2.5xCD show muscle degeneration.
