A point mutation has been introduced into the active site (amino acid replacement E510A), resulting in a catalytically inactive protein.
Adults expressing Hsap\GYS19AD.Scer\UAS under the control of Scer\GAL4elav.PU during the adult stage show a slight decrease in lifespan compared to controls.
Expression of Hsap\GYS19AD.Scer\UAS under the control of Scer\GAL4ple.PF has no significant effect on lifespan.
