Figure 10. Further characterizing how bidirectional COPI transport at the Golgi is regulated.
a, Summarizing how external stimuli regulates bidirectional COPI transport through a signaling cascade. b, Effect of Src activation on the intra-Golgi transport of VSVG. Colocalization is exemplified by line scanning across representative images (out of 5), bar = 5 um. Quantitation is also shown, n = 3, mean +/− s.e.m.
