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.

Comprehensive ubiquitin E2 profiling of ten ubiquitin E3 ligases.

Marblestone JG, Butt S, McKelvey DM, Sterner DE, Mattern MR, Nicholson B, Eddins MJ

The ubiquitin pathway regulates diverse functions including protein localization and stability. The complexity of the pathway involving nearly 40 identified E2 conjugating enzymes and over 600 E3 ligases raises the issue of specificity. With the E2s and E3s fitting into a limited number of classes based on bioinformatics, structures, and proven activities, there is not a clear picture as to ... [more]
