    (A) Representative time-lapse images showing breakage of the connection between the growing tip of a newly-formed ER tubule (magenta) and a lysosome (green) in EGFP-VAPA(KD/MD)-expressing cells. See table S2 for the compromised contact sites upon VAPA(KD/MD) overexpression. See Movie S5. (B) Average velocities (black spots) of initially ER-tethered lysosomes that become detached (red arrow) from their associated ER growing tips. Detachment events are ER-lysosome connection breakages in EGFP-VAPA(KD/MD)-expressing cells as in (A). **= p<0.01, **** = p<0.0001 (Tukey’s one-way ANOVA). Velocities of 22 events from three independent experiments were quantified. See table S3.

Right: Percentage of the ER comprising tubules upon knockdown of lysosome motion adaptors. Data are shown as ± SEM. **** = p<0.0001 (Tukey’s one-way ANOVA).

Data are shown as ± SEM. **** = p<0.0001 (Student’s t test).
