F. Representative images of Sec24C localization at SGs (stained for G3BP) in TRAPPC3-KD and TRAPPC2-KD cells treated with SA. Depletion of the entire TRAPP complex (via TRAPPC3 depletion) or of only TRAPPC2 reduces Sec24C recruitment. Graph, quantification of Sec24C at SGs, calculated as in (E). Mean ± s.e.m., n = 40-60 cells per experiment, N = 3. ****p< 0.0001, One-way ANOVA with Dunnett's multiple comparison test. Data information: Scale bars, 10 µm.
