Ectopic expression of VSR5:HA increases the secretion of cargo proteins in vsr1vsr4 double mutant protoplasts. A and B, Effect of VSR5:HA expression on the trafficking of AALP:GFP and phaseolin in the vsr1vsr4 double mutant. Protoplasts derived from vsr1vsr4 mutant plants were cotransformed with the indicated amount of VSR5:HA together with either AALP:GFP (A) or phaseolin (B). Protein extracts from transformed protoplasts (P) and incubation medium (S) were analyzed by western blotting using anti-GFP or antiphaseolin antibody. Expression of VSR5:HA was detected by anti-HA antibody. Actin was detected as a control for protein leakage from protoplasts and as a loading control. Pre, precursor form; Pro, processed form.
