Figure 2. Mutations in Drosophila genes encoding homologs of mammalian PSD proteins lead to an increase in GluRIIA cluster sizes.

Figure 2

(A) Representative confocal micrographs of 6/7 NMJs immunolabeled with α-HRP to label presynaptic motor neurons (magenta) and α-GluRIIA (green) to label GluRIIA-containing glutamate receptor clusters. Inset panels show high resolution terminal boutons. Scale bar = 20 µm. (B) Quantification of GluRIIA cluster sizes for genotypes shown in A. (C) Quantification of characteristics representative of presynaptic motor neuron morphology including the number of boutons (left) and branches (right).
