Genomic fragment derived from the CH322-20H13 BAC clone) that encompasses Gcn2. A 1375bp deletion that removes sequences from exons 5 to 8 and which spans the kinase domain has been introduced.
Unlike wild-type flies, Gcn25'Δ;Df(3R)Gcn2-FRT12kb/Df(3R)Gcn2-FRT12kb ('rescue') mutants fail to display the normal lifespan extension associated with a low-protein diet.
