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.

Protein Phosphatase-1 Complex Disassembly by p97 is Initiated through Multivalent Recognition of Catalytic and Regulatory Subunits by the p97 SEP-domain Adapters.

Kracht M, van den Boom J, Seiler J, Kroening A, Kaschani F, Kaiser M, Meyer H

The AAA-ATPase VCP/p97 cooperates with the SEP-domain adapters p37, UBXN2A and p47 in stripping inhibitor-3 (I3) from protein phosphatase-1 (PP1) for activation. In contrast to p97-mediated degradative processes, PP1 complex disassembly is ubiquitin-independent. It is therefore unclear how selective targeting is achieved. Using biochemical reconstitution and crosslink mass spectrometry, we show here that SEP-domain adapters use a multivalent substrate recognition ... [more]
