Figure Legend Snippet: Figure 3. PITPβ promotes contact between the ER and COPI buds on the Golgi. Quantitative data are shown as mean ± SD, with the number of in- dependent experiments indicated. Statistics was performed using the two-tailed Student’s t test: ****P < 0.0001, ***P < 0.001, **P < 0.01, ns (non-significant) P > 0.05. (A) Colocalization of PITPβ with ER marker (Sec61β) and Golgi marker (giantin) as assessed by confocal microscopy using Airyscan, PITPβ (blue), Sec61β (green), giantin (magenta), n = 6. Representative images with scale bars are shown with inset highlighting PITPβ colocalizing with both Sec61β and Giantin (indicated by arrowheads). A reconstruction of this region is also shown, with a line scan along the dotted line providing quantitative information, as well as single-channel images. (B) Airyscan confocal microscopy examining the effect of siRNA against PITPβ on the colocalization of an ER marker (Sec61β) and a Golgi marker (Giantin). Quantitation of a representative experiment is shown, n = 3. (C) Airyscan confocal microscopy examining the effect of siRNA against PITPβ on the colocalization of an ER marker (Sec61β) and a TGN marker (TGN46). Quantitation of a representative experiment is shown, n = 3. (D) EM tomography showing COPI buds at the Golgi in close proximity to the ER membrane. A representative tomographic image slice is shown in the upper left panel with arrowheads pointing to COPI buds, bar = 200 nm. 3D reconstruction of the Golgi, COPI buds, and ER elements is shown in the lower left panel. Quantitation of a representative experiment is shown on the right, comparing the distance between COPI buds and ER membranes versus the distance between Golgi cisternal margins and ER membranes, n = 3. (E) Proximity ligation assay examining the effect of siRNA against PITPβ on the proximity between calnexin and giantin. Quantitation of a representative experiment is shown on right, n = 3. Representative confocal images are shown on left, PLA signal (red),
