Reconstituted Complex

An interaction is inferred between proteins in vitro. This can include proteins in recombinant form or proteins isolated directly from cells with recombinant or purified bait. For example, GST pull-down assays where a GST-tagged protein is first isolated and then used to fish interactors from cell lysates are considered reconstituted complexes (e.g. PUBMED: 14657240, Fig. 4A or PUBMED: 14761940, Fig. 5). This can also include gel-shifts, surface plasmon resonance, isothermal titration calorimetry (ITC) and bio-layer interferometry (BLI) experiments. The bait-hit directionality may not be clear for 2 interacting proteins. In these cases the directionality is up to the discretion of the curator.

Screening of Hsp105alpha-binding proteins using yeast and bacterial two-hybrid systems.

Saito Y, Doi K, Yamagishi N, Ishihara K, Hatayama T

Hsp105alpha is a 105-kDa stress protein, which is expressed constitutively at especially high levels in the brain compared with other tissues in mammals, and is also induced by a variety of stressors. Recently, we have shown that Hsp105alpha binds to alpha-tubulin and prevents the heat-induced disaggregation of microtubules. To further elucidate the function of Hsp105alpha, we searched for Hsp105alpha-binding proteins ... [more]

An interaction is inferred when a bait-enzyme fusion protein selectively modifies a vicinal protein with a diffusible reactive product, followed by affinity capture of the modified protein and identification by mass spectrometric methods.
