UASt regulatory sequences drive expression of full-length His2Av that has been mutated to carry a S137E amino acid replacement (phosphomimetic mutation at a phosphorylation site).
His2AvS137E.UAS/Scer\GAL4arm.PS rescues His2Av810
Expression of His2AvS137E.Scer\UAS under the control of Scer\GAL4arm.PS rescues the viability of His2Av810 flies exposed to 36Gy (gamma irradiation).
