Suppressors separated according to classes. Amino acid changes accounting for the suppression phenotype are shown. Suppressor stocks were maintained as recombinants with the GMR-GAL4 driver (stock), which were crossed to CY2-GAL4 to test suppression in the ovary. Eye phenotypes are classified as a range between mild roughness (R1) and severe roughness with a decrease in eye size (R4). Likewise, chorion phenotypes are classified according to the degree of ventralization, ranging from weak (V1) to complete ventralization (V4). GFP localization was followed in somatic follicle cells. Normal apical localization is observed with the control Kek1-GFP protein and class I suppressors, whereas class II suppressors display abnormal cellular distribution (mislocalized).
