Amino acid replacement: S137E.
UAS regulatory sequences drive expression of full-length His2Av coding sequences containing a mutation that affects a phosphorylation site, mimicking constant phosphorylation.
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).
