Summary of the proteins identified in G2A Naked2-associated vesicles. A, 389 proteins were identified in Pool 2 G2A Naked2-associated vesicles by LC/LC-MS/MS in three independent experiments. A total of 767, 480, and 496 proteins were identified in the three experiments from 1.75 × 108, 6.5 × 107, and 9.4 × 107 flow-sorted vesicles, respectively. The numbers 67, 23, and 81 represent overlapping proteins between two different experiments, respectively. B, functional classification of the 389 proteins found in all three experiments.
