The genotype, GAL4 driver enhancer sequence, or site of insertion, predicted protein role, and expression pattern revealed by crossing to UAS-CD8-GFP for third instar larvae is shown for the six lines identified with motoneuron-restricted expression. GMR94G06 and 6-58 are referred to as MN1-Ib GAL4 and MNIs GAL4, respectively, throughout the article.
