⍺TAT1 is required for neuronal ⍺-tub^K40Ac and normal touch-evoked behavior. (A) Immunofluorescence of zebrafish trunks at 6 dpf stained for ⍺-tub^K40Ac and neurofilament (NF). Scale bar, 50 μm. (B) Still images from touch-evoked escape assays in 6 dpf wild-type siblings and atat1 mutants. t = 0s marks the first tail stimulus; subsequent stimuli in atat1 mutants occurred at 2.0 s and 3.1 s. Scale bar, 1 mm. (C) Immunofluorescence of the Mauthner circuit at 6 dpf. Laterally projecting cranial nerves can be observed flanking Mauthner axons. Scale bar, 20 μm. (D) Quantification of touch responsiveness. A significantly greater proportion of atat1 mutants failed to respond compared with wild-type siblings (n = 16 per group; P = 6.8 × 10⁻⁵, chi-square test). (E) Swim distance following touch-evoked responses. Dots represent individual fish and error bars show standard deviation. P = 0.6 (unpaired t-test). (F) Swim velocity following touch-evoked responses. Dots represent individual fish and error bars show standard deviation. P = 0.55 (unpaired t-test).
