Supplementary Figure 1: An N-terminal domain of kainate receptor subunit 2 is retained in the soma

(a) A hippocampal neuron expressing GFP. (b) A hippocampal neuron expressing KA2-GFP. (c) A hippocampal neuron expressing KA2(1-150)-GFP. Scale bars for a-c: 50 µm. (d, e, f) Box-and-whiskers plots of GFP brightness versus position along a neurite, normalized to GFP brightness at the soma for GFP (n = 5 neurites from 3 cells), KA2-GFP (n = 5 neurites from 3 cells) and KA2(1-150)-GFP (n = 5 neurites from 3 cells) respectively. Red line denotes the median. Top and bottom edges of the box indicate the 75th and 25th percentiles, respectively. Top and bottom whiskers indicate the highest and lowest values respectively. See Supplementary Table 2 for Bonferroni-corrected Kolmogorov-Smirnov tests for Figure S1.
