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.

c-Fos proteasomal degradation is activated by a default mechanism, and its regulation by NAD(P)H:quinone oxidoreductase 1 determines c-Fos serum response kinetics.
The short-lived proto-oncoprotein c-Fos is a component of the activator protein 1 (AP-1) transcription factor. A large region of c-Fos is intrinsically unstructured and susceptible to a recently characterized proteasomal ubiquitin-independent degradation (UID) pathway. UID is active by a default mechanism that is inhibited by NAD(P)H:quinone oxidoreductase 1 (NQO1), a 20S proteasome gatekeeper. Here, we show that NQO1 binds and ... [more]
