Comments concerning this interaction

Source was cell extract of S2 cell line; bait produced from transfected construct; prey produced from transfected construct.

Vps52 specifically binds the GTP-bound state of Rab4 (not the GDP-locked form).

Comments concerning this interaction

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

Specificity S-score=13.78.

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.

Comments concerning this interaction

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

Specificity S-score=11.75.

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.
