Interaction in vitro; bait produced as a recombinant fusion protein in bacterial system; prey derived from S2 cell extract (endogenous gene).

Specificity S-score=15.19.

Constitutively active (GTP-locked) form of Rab was used for pull down. Parallel pull downs performed for several Rabs proteins in this study. Yield was measured using spectral counts. A specificity score (S score) was calculated, where greater weight was given to interactions seen with fewer baits.
