Mutation of KLC1 serine-460 to mimic permanent phosphorylation, inhibits axonal transport of APP in cultured rat cortical neurons. (a) Representative kymographs showing axonal transport of APP-EGFP in APP-EGFP+KLC1wt and APP-EGFP+KLC1S460D co-transfected neurons; scale bar and times are indicated. Bar charts show % for total, anterograde and retrograde APP-EGFP movement. N = 17 EGFP+KLC1wt and 20 APP-EGFP+KLC1S460D co-transfected neurons. Statistical significance was determined by Student’s t-test. Error bars are s.e.m.; **p < 0.01; ns not significant. (b) Violin plots show velocities of APP-EGFP movement in anterograde and retrograde directions in the different transfected cells. Median and interquartile ranges are indicated by hashed lines. N = 163 anterogradely and 62 retrogradely moving APP-EGFP in KLC1wt and 179 anterogradely and 54 retrogradely moving APP-EGFP in KLC1S460D co-transfected cells. Statistical significance was determined by Mann-Whitney U test; ns not significant
