Genomic fragment derived from the CH322-20H13 BAC clone) that encompasses Gcn2. A 1040bp deletion that removes sequence encoding the tRNA-binding domain from exons 8 to 9 has been introduced.
Unlike wild-type flies, Gcn23'Δ;Df(3R)Gcn2-FRT12kb/Df(3R)Gcn2-FRT12kb ('rescue') mutants fail to display the normal lifespan extension associated with a low-protein diet.
