Expression of pathogenic (CCUG)106 increases PKR activity in retinae of GMR>DM2-106 flies. The posterior portions of eye imaginal discs from third instar larvae of the indicated genotype labeled with phospho-specific eIF2α (P-Ser51) antibody to detect PKR activity. GMR-Gal4>UAS-N-16 (A,B) or GMR-Gal4>UAS-DM2-106 (C,D) discs were treated (B,D) or not (A,C) with 7 μM PKR-I.
