Fig. 2 The coa Mutant Gene Encodes β-SNAP1(A) A non-sense mutation occurs at 152Y in β-snap1 gene in the coa mutant.(B) There are four zebrafish snap genes: two α-snap and two β-snap genes. β-SNAP1 has 90.8% amino acid identity to β-SNAP2, whereas β-SNAP1 has 78% and 73% amino acid identity to α-SNAP1 and α-SNAP2, respectively. In accordance with the evolution tree, zebrafish α-snap2 gene is positioned outside the human α-snap gene. Zebrafish β-snap genes seem to be duplicated after separation from human β-snap gene. sec17p is a yeast α-SNAP homologous gene. (C) Labeling of 84 hpf WT, coa mutant retinas, and coa mutant retinas expressing β-SNAP1 with zpr1 antibody (green) and GFP-tagged peripherin (magenta). Middle panels show higher magnification of the outer photoreceptor layer. Lower panels show the magenta channel. Scale bars, 50 μm (upper panels) and 10 μm (middle panels). See also Figure S2.
