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.

The yeast galactose genetic switch is mediated by the formation of a Gal4p-Gal80p-Gal3p complex.
Saccharomyces cerevisiae responds to galactose as the sole source of carbon by activating the GAL genes encoding the enzymes of the Leloir pathway. Here, we show in vitro that the switch from repressed to activated gene expression involves the interplay of three proteins [an activator (Gal4p), a repressor (Gal80p) and an inducer (Gal3p)] and two small molecules (galactose and ATP). ...
