Figure 3-figure supplement 2. GluR2/3 localization is unaffected in ZO and Connexin mutants.

(A–D) Confocal images of Mauthner CEs in 5-day-post-fertilization, zf206Et zebrafish larvae from wt (A,C), tjp1b/ZO1b-/- (B), and gjd2a-/-; gjd1adis3/dis3 (Cx35.5/Cx34.1, respectively) mutant animals (D). Animals are stained with anti-human-ZO1 (magenta) and anti-rabbit-GluR2/3 (white), and images depict a single z-slice. Arrowheads highlight location of chemical component of mixed electrical/glutamatergic synapse. Scale bar = 2 µm.
